The L-lense that puts the L-lense on the map
By J. Chen
Canon's legendary L-lense reputation is built on lense such as the 70-200mm F/2.8, this is the lense that gives the credit to the WOW factor associated with Canon L lense. Sharpness, constrast is second to none.

I know many people are probably deciding between the F/4L F/2.8L and the F/2.8L IS. If you want the most bang for the buck go for the F/2.8L. Why, because if you're serious enough to buy the F/4L you will eventually migrate to this F/2.8L (like many photographers), why because there is nothing going to speed up your shutter speed better than the f/2.8 at the long end when compared to F/4 especially for fast moving targets. Another big advantage is the canon 2x extender which boost this lense to 400mm at the long end with great results and at F/5.6, it is one of the best performing combo at 400mm focal length especially considering the price of a 400mm lense by itself.

If you have cash to burn go for the IS version, but cost increase is a bit steep ($500+), especially considering using a tripod will make the IS an non-issue, and for a shot deserving attention, a tripod or some sort of stablizer should be used anyway might as well save the $500 and put a bit more in for the 17-40mm L lense. :-)

You get what you pay for
By Colin M. Burnett
This was my first L lens and I am very pleased; zero buyer's regret for me.

When I first started to seriously consider buying one of the 70-200mm lenses I wasn't sure which to buy. I first thought about buying the f/4 version because it was cheaper but then found out the f/2.8 comes with a case (~ $40), tripod ring (~ $120), and a hood (~ $35) in addition to the extra stop in aperture. For the $600 difference it reduces down by about $200 by including additional stuff that you, frankly, should have.

Most notably is the tripod ring which takes the lens weight off the camera body but also balances the camera at the tripod mount. With the f/2.8 attached to my 300D it balances just fine on the tripod foot (even with a EX550 flash). In shooting with a tripod it's very easy to rotate the lens within the ring to go from landscape to portrait without off-balancing the weight.

The extra weight is an issue depending on your muscular build. I can shoot for a couple hours without the weight being bothersome but my fiancee (very petite) has some difficulties. In actual shooting I find the tripod ring comes in handy to put the weight on my palm thus leaving my fingers free to adjust zoom and focus without a hassle while providing a firmer base for stability.

I cannot comment on the f/2.8 IS version since I've never used it but I have seen people selling their f/2.8 IS because it was too heavy.

All-in-all this is an extremely good lens and you get exactly what you pay for: quality. Some day I intend on complementing this lens with the 24-70 f/2.8L for wider angle shots. Of course, if you have the chance to test all three versions of the 70-200mm lens at a store then you certainly should test them for yourself. And, by all means, buy a UV/protector lens.

Auto-focus is super fast, quiet and spot on
By Grant Brummett
01-01-2009 Canon 5D Mark II Update

Bokeh

Well, the reach my be less but man on man the Bokeh of this lens using the 5D Mark II has to be seen to be believed. Much smoother creamier and richer on the 5D Mark II. Something like double the Bokeh since you can get twice as close, just make sure when shooting at F/2.8 you have enough dept of field.

Sharpness and clarity

The sharpness and clarity wide open at F/2.8 that was just Ok on the 40D is much improved for some strange reason on the 5D Mark II. I would not have figured it this way but it's just plain better. Putting this lens on the 5D Mark II has transformed it from a so so lens to a sharp, high clarity monster even wide open. You wouldn't know it was the same lens I has used on the 40D.

Reach:
The reach of the lens on a full frame sensor camera is half but when indoors shooting weddings this can be a good thing. On the cropped sensor cameras you often find yourself running out of space to back up when you want a wider shot but on the 5D Mark II the 70mm end is actually useful. When shooting outdoors if you can't get pretty close you will want a longer lens. This is when I reach for my excellent Canon 100-400 F/4.5 - F/5.6 IS L Lens.

Vignetting:
On my Canon 40D and Rebel XTi Vignetting or peripheral illumination problems are practically non-existent, but on my new Canon 5D Mark II I use the auto-peripheral illumination correction as with it off it is a problem. But with it ON its no problem at all.

You can either have the 5D Mark II auto-correct peripheral illumination on board for JPEGs or adjust Raw images using Canon's Digital Photo Professional (DPP) software that came with your Mark II. I have noticed on the full framed 5D Mark II with the peripheral illumination correction turned OFF the 5D Mark II images will severely vignette or be dark in the corners when shot wide open (F/2.8). It's almost like looking through a dark tunnel. It's especially noticeable shot wide open with the sky as a background.

Auto-correct to the rescue!! With the peripheral illumination correction turned ON it's almost magical the darkening in the corners for your JPEG images is gone! If you want you can even shoot in Raw mode and adjust the amount of Vignetting or darkness in the corners for effects such as when shooting portraits and you want to emphasis the person in the middle of the photo. Just open the Raw photo in DPP and click on the NR/Lens / ALO tab and select Lens Aberration Correction Tune and adjust the peripheral illumination to suite by dragging the slider or entering and amount. Or select all the photos in a directory and you can correct all your photos at once. This way you can either have no Vignetting or as much as you want.

Pros:

Tack Sharp at 70-135mm at F5.6 at any distance
Sharp at F2.8 at a distance for some reason but soft up close (10 to 50 feet)
Sharp at F2.8 for indoor non-flash gym / church distance photos any zoom setting. Gets a little soft focused close and at infinity at F2.8
Auto focus tracks moving objects like a laser guided smart bomb! I have many in flight bird photos
Beautifully made with perfect quality
Beautiful deep colors, lots of contrast
Auto-focus is super fast, quiet and spot on even in dim light
White so it's cooler out in the hot summer sun
Comes with nice case and nice lens tripod mount
Pretty good Bokeh better then the F4 70-200 of course but not as good as primes
Really bright in the viewfinder the brightest long lens I've used
This lens has Auto Lens Vignetting correction using peripheral Illumination control see Auto Vignetting comments below:

Cons:

VERY shallow depth of field at F2.8
Costs twice as much as the great F4 70-200
Seems to weigh twice as much as the F4 70-200
Very LARGE and white gets a LOT of attention
Softens a little above 135mm approaching and at 200mm at infinity

Review:

I bought this Lens to use on my Canon Digital Rebel XTi to shoot wild birds, animals at the zoo, sporting events and aircraft shows.

After having taken over 4,000 photos with it and trading out and using my friends F4 70-200 I have the following conclusions.

This lens focuses very FAST!! I have tracked birds in FLIGHT!! It focuses in light so low I don't see how it's focusing.

The F2.8 is MUCH larger then the F4 you have to use these two lenses back to back to really appreciate the difference. Also the lens hood sticks way out on the F2.8 which does protect the lens more but makes a long lens even longer. The F4 is more of a hold all day out shooting lens for the average person the F2.8 more of a tripod lens.

I do love this F2.8 lens, but in hindsight I might have bought the cheaper lighter and smaller non IS F4 lens. We tried several tests using a tripod while using mirror lockup and remote release so camera shake and depth of field were not a variable. We found my F2.8 lens is slightly sharper in the middle at 200mm but the F4 is slightly sharper near the edges. Both lenses were tack sharp edge to edge at 70-135mm at F8 with the F4 lens maintaining more sharpness over all from 135 to 200mm. However I found the F2.8 is brighter looking through the view finder then the F4.

The F2.8 does seem to produce slightly richer color but you can easily make up the difference between the F4 in a photo editor program.

This lens also softens some at F2.8 and gets sharper the closer to F8 you get. I tried several test shots on a tripod using mirror lockup and remote release of a photo test card so camera shake and depth of field were not a variable. Speaking of depth of field at F2.8 the depth of field is so shallow at close range F2.8 is almost unusable. You can take a photo of someone and their nose is tack sharp and their eyes are soft. This could be a plus if you are looking for this effect.

So why do I keep this lens?

I shoot a lot using a tripod and love the included lens tripod mount. The camera and lens are MUCH more stable when the lens is mounted to the tripod then trying to shoot with a long lens with the camera mounted to the tripod and the lens hanging out front. Note: You can buy the lens tripod mount for the F4 lens but it's $150 extra.

I need the extra stops F2.8 gives me for low light indoor photograhy I have gotten shots at F2.8 ISO 1600 I could not have gotten with the F4 lens.

I do like the attention I get and questions.

I love the way this lens is SO bright in the viewfinder, noticeably brighter when framing a shot then the F4.

I don't mind the extra workout carrying it around I need the exercise.

I'm thinking about also buying the F4 70-200 and having both.

Why only 4 stars:

If this lens were tack sharp edge to edge at 200mm at any distance I would have given it 5 stars but felt that this was enough to pull back to 4.
Also the min distance switch is too easy to move, it doesn't need this switch anyway the auto focus is great,

Recommendation:

If you have the money and want a bright in the viewfinder, great color, large, imposing presence tripod mounted lens the F2.8 lens is for you.

If you want to save some money and shoot hand held with a lighter lens and don't need the F2.8 for low light shooting and Bokeh then get the F4 lens.

If you have lots and lots of money buy them both!

9-23-2007 Update

This lens continues to impress me. I have been shooting more around F2.8 at longer reach hand held on cloudy days and inside buildings where flash is not allowed and have found this lens really can work hand held at higher ISO say 400 to 800. I'm thinking about buying the 40D which has higher ISO performance then my Rebel XTi so I can shoot at 1600 ISO and 3200 ISO with less noise.

Filter Update 1-3-2008

After much searching I found the perfect filter. The Hoya Multi Coat HMC Pro1 Protection filter is not supposed to filter the shot just protect the front lens element. I was very worried that it would affect the shot after having tried some other premium filters like the B+W UV which caused the photos to be softer and duller. However, after some tests I found that in some weird way the Hoya Multi Coat HMC Pro1 actually makes the photos seem to have just a little more contrast and be a little sharper then without. I thought I had gotten the test shots backwards and had to retest with a little sign in the photo saying with and without filter in place just to make sure. Really amazing!!! I'm sold!

Update 3-1-2008 Arizona Renaissance Festival

Here's a brief summary of my thoughts when using both the Canon 70-200 F/2.8 USM L and Canon 135mm F/2 USM L at AZ Renaissance Festival.

The first thing I noticed was the zoom can be much more versatile especially at the bird show where it's ability to zoom in and out was nice, but it's minimum focus distance is quite a bit farther. I noticed several times taking face shot close ups that I ran into the stop and it could not focus, so I had to back up. Also knowing that full sharpness was not reached until F/5.6 I kept the lens at this stop to make the shots sharp. But there is no denying its ability to reach out and photograph someone at a distance and then turn around and get a shot close up. Also, the Canon 70-200 really stood out to people. I actually had several people ask what lens it was and could they look at it / hold it. Several workers made jokes about my large canon when I had it mounted.

On the Canon 135mm side there is no denying the quality of the photos and the ability to blur the background and still have a sharp subject at wide open apertures. The creamy smooth Bokeh and quality of the photos make them treasures I will show off and print for years to come. There is some 3d quality that these photos possess that the 70-200 just does not have. The Canon 135mm is much more stealthy with people not really thinking you are taking their photo from far away. No one asked to hold it or even what kind of lens it was. The workers didn't make jokes about having a large canon in fact there were a couple of workers that said they had seen bigger.

I love them both, but if I had to choose only one to take to the Renaissance Festival it would be the Canon 135mm F/2 USM L. It's half the weight, black and stealthy and takes photos I will treasure forever.

3-28-2008 Update:

I still love this lens and it was my first L lens. It's funny how much more attention this lens will get everywhere I go. You will be asked what news agency you are working for, can I see it, can I hold it, how much does it cost? Things I have never been asked about my Canon 85mm F/1.2 L II lens which cost hundreds more. So if you want a great 70-200 zoom and crave attention and can carry the weight this lens is for you. I still love mine and plan on keeping it forever!

8-18-2008 Update:

I find myself falling in love with this lens all over again. A friend has borrowed it for a few months to use and I went on a shoot this weekend with it and wow!! When you use Digital Photo Professional (DPP) to make your JPEG from RAW this lens is a razor blade even at F/2.8! There is that much difference in processing using DPP then usin Adobe Camera Raw!!! It makes my Canon 70-200 F/2.8 look almost as sharp as my Canon 135 F2.

The only strange thing when I first got the lens back it focuses more slowly then normal for a few shots about like the focusing on my Canon 85mm F/1.2 which can be a little slow. But within a few hundred shots seems to be back to the milisecond focus speed. I wonder if he left it out in the car in the hot Arizona sun?

Still get's a huge amount of attention. You would think it was a Canon 300mm F/2.8 the way people stare. Guess the white L lenses are still pretty rare out and about. My friends Canon 70-200 F4 L is just as sharp but the F/2.8 lets in twice as much light! But the F/2.8 feels almost twice as fat in the hand and after a day of shooting is heavier!! Still when I was already at ISO 3200 and F/2.8 yeasterday at a very dark church function I was stopping action that you could not do with the Canon 70-200 F/4.

11-07-2008 Update:

This is still one of my most used and versatile lenses. And I've noticed in some of my photos this really cool almost 3D effect around the main subject usually at wider apertures. My only regret is that it does not have IS. After buying two lenses that have it I can see that in really dark situations IS can really make a huge difference. Also there is the one single spec of dust in the middle of the outer most element. But it does not seem to affect the photos.

It's taken many beautiful photos for me and I will probably keep it as long as I live.

Auto Vignetting peripheral illumination control:

Canon has this super sweet Auto Lens Vignetting correction that works with this lens both in camera with JPEG's and in RAW using peripheral Illumination control in Canon Digital Photo Professional (DPP) when using newer Canon digital EOS cameras (Canon Rebel XSi, 40D, 5D Mark II etc.) . No more vignetting when shooting wide open!!! When shooting Raw open the file(s) in DPP and click on NR/Lens Lens Aberration Correction / Tune and click on Peripheral illumination. The cameras listed above have already picked up the amount of vignetting based on focusing distance, zoom setting and F stop from the lens and the camera has saved the information with the Raw file. You can then adjust the amount under Peripheral Illumination if you don't like the amount automatically suggested. If you shot JPEG then you get the auto amount. SWEET!!!

Verdict:

You can't go wrong if you need 70-200mm and fast speed.

01-03-2009 Canon 5D Mark II Update:

This lens is actually just behind my Canon 100-400 IS L Lens in the zoom sharpness and clarity department but it's no where near as versatile on my 5D Mark II as the 100-400. Still it's a must have lens when shooting weddings when you need the super Bokeh background melting power of an F/2.8 aperture and lower light power of an F/2.8 aperture. The Bokeh that was Ok on the 40D is smoother creamier and richer on the 5D Mark II. Still I almost wish I had bought the Image Stabilized version instead. I'm finding that on the 5D Mark II you can really sharpen up images when shooting in raw and processing in Canon's Digital Photo Professional. As that and the price were my only complaint about the IS version of this lens I now wish I had purchased it instead.

Lenses I currently own:

Canon EF-S 17-55 F/2.8 IS Zoom Lens Ultra sharp, great colors, great low light, poor zoom action
Canon EF-S 18-55mm f/3.5-5.6 Rebel XTi Kit Zoom lens Muddy, slow, pile of junk
Canon EF 17-40mm f/4 L Zoom Lens Fantastic colors, sharp zoomed 17 to 24mm and stopped down, ultra smooth zoom action, light weight
Canon EF 24-70mm f/2.8 L Zoom Lens Fantastic colors and contrast, sharp zoomed 40 to 70mm, zoom a little stiff at first, heavy, repair prone!
Canon EF 50mm f/1.8 II Good budget portrait lens, light weight, disposable, sharp from F/2.5
Canon EF 85mm F/1.2 L II The best portrait lens for female and children clients, buttery smooth Bokeh, heavy and expensive it shares sharpness with 135mm
Canon EF 135mm F/2.0 L The best portrait lens for males and tied with Canon 85mm F 1/.2 for sharpest lens I own, buttery smooth Bokeh
Canon EF 70-200mm f/2.8 L Zoom Lens Fantastic colors, sharp for a zoom, very versatile ego boosting and attention getting and heavy! My favorite zoom lens that I own!!!
Canon EF 100-400mm f4.5-5.6L IS Zoom Lens super colors, sharp for a zoom, extremely versatile, variable Bokeh can be great or bad, even more ego boosting and attention getting when extended and 400mm reach!!

My next lens purchase I'm saving for right now: 'Canon EF 300mm F/2.8 IS L the finest lens ever

The answer to the crop sensor problem.
By Jim Krupnik
My take on this lens is that it is an "L" quality optic in a fine, non "L" package. There is nothing else on the market to compete with it (nothing at all), and it produces supurb images. It isn't an f/2.8 lens, but it is close enough for most uses. The competition from Tamron is a full stop slower, not as sharp, and is awful in dim light compared to the Canon 10-22 lens (sorry, Tamron fans, but the Tamron lens isn't even playing in the same ballpark).

I use this lens on a 30D body, and I always keep it on hand if I'm doing any indoor, or tight group photography. It is the perfect solution to the perennial problem of not having enough room to capture all the kids at a birthday party in one shot because your back is up against a wall. This lens will just about get your toes into the picture at the widest setting, yet delivers tack sharp, colorful, and contrasty images. The auto focus is spot on, silent, and fast. It is a must have lens for the active amateur, or any pro using a 1.6 crop factor camera. You simply can't beat this lens with anything available on the market today.

That beng said, do not try to convince yourself that this will make a good "walkaround" lens. It isn't. Even at max length, it is far too short to live on your camera as a standard lens. You need this lens, even if you don't know it yet, but it should not be your first lens, as it will only be used 15 to 20 percent of the time. At those times, it's performance simply cannot be equaled by any other zoom lens on a 1.6 crop factor camera. You will be amazed by the quality of this lens. It rivals the performance of modern prime lenses, presents a bright viewfinder image, and delivers the goods in tight situations.

This is not a casual assessment, nor a Canon "feel good" moment on my part. I developed my first B&W contact prints in 1964, in my own darkroom at the age of 9 (my parents were concerned:)), and have been an avid photographer ever since. Small, medium, and large format cameras and lenses have passed through my hands over the years, and Canon has become my favorite small format brand. Still, Canon builds some trash lenses that should be avoided. The 10-22 USM is not one of them :).

Before you go out and buy this lens, you should already own the EF-S 17-55mm IS f/2.8 lens. That is the king of 1.6 crop factor standard lenses, and includes the awesome Canon IS feature. It will end up being mounted on your camera 80% of the time, and keep you smiling after every shoot. Get that lens first. Then, get the 10-22mm lens. Then, let your imagination run wild, and plan on serious telephoto lenses for the future. Trust me or not, the two lenses mentioned above will provide you with photographic tools that will astound you. Get them in your kit as soon as you can afford them.

A little warning about either lens.... Some here will argue the point, but with either lens, get a GOOD quality UV filter that is multi-coated on both sides, and built extra thin to avoid vignetting at wide lens settings. A good filter will cost a little less than one hundred Dollars, and can cost up to one hundred forty Dollars. The minimum brand would be Hoya Pro 1 multi coated filters, and the ante goes up from there.

Everything else is garbage, including the Canon "sharp cut" filter that costs less than fifty bucks. No kidding, no conjecture. If you use cheap filters, you will never see what your lens can really do. Ever. No doubt that many will respond with claims that their twenty Dollar filter works just fine, but they simply don't know any better, and have never used their expensive equipment to it's full potential. It's akin to a Chevy owner passing judgement on a Mercedes Benz. The Chevy might feel real good, but until you own the Mercedes, you just have no clue.

Bottom line.... Make sure that the quality of your filters exceed the quality of your lenses. Yes, at a hundred bucks a pop for a 77mm filter, it hurts, but you will never regret it. Also, Amazon does not stock lens hoods for all non L Canon lenses. The price is stupid high for those hoods, but they make a night and day difference in in picture quality. Whenever you order a non L Canon lens, find a web seller who has the hood in stock, and get it right now. Again, you will never regret owning it.

That's it for my review/rant. Buy this lens. Buy the 17-55 IS f/2,8 first. Buy the lens hoods for both. Toss any "kit" lenses that came with the camera in the trash bin (where they belong), and be very happy.

The best lens I own
By M. A. Filippelli
I have had this lens for several months now and let me start out by saying WOW. I looked at the lens in the store along with the Sigma 12-24 and I was in total awe of what I saw though the view finder with the Canon 10-22. This is an ultra wide angle lens that is incredible. I went home and thought about where I would use this lens and determined that I would use it quite a bit. I went ahead and bought the lens and I continue to be more impressed with it every time I use it. I have used the lens for both close-up (which can give you some very interesting distortion shots)and wide angle shots with great success.

The 10-22mm is equivalent to 16-35mm field of view using a canon 20D which is not a full frame sensor. With a minimum focal distance of .24m (about 9.5 inches) you can get very close to objects and still get alot of focal width in the photo. There is incredible clarity in the lens. The photos I have taken are very clear with only a slight hint of softening at the corners at 10mm; everything else is sharp after that. There is a little barrel distortion at 10mm but everything else up to 22mm is nice. I have not gotten any light flare in my photos. The Ultrasonic motor is very quiet. The depth of field is outstanding. A slim UV filter helps prevent some slight vignetting at 10mm. With a maximum aperture that ranges from f/3.5 to f/4.5, the Canon EF-S 10-22mm f/3.5-4.5 USM Lens is a medium speed lens. I would recommend using a tripod if you are at all unsure about your ability to hold the camera still for action shots with this lens. The lens it's self is fairly light weight. If you are going to use filters the lens requires 77mm.

The lens can produce some interesting distortion shots if you are taking close-ups and are not perpendicular to the object. For close-up shots with out distortion it is best to be perpendicular to the object.

Inside the lens housing there are three aspherical lens elements and a Super UD element that produce clear vibrant shots. The lens it's self sturdily built and comfortable to handle.

UPDATE 7/30/2011: I still love this lens. It functions every bit as well as it did the day I got it.

Very good lens, but expensive
By Svend
I am very impressed with this lens. I didn't realize just how wide-angle this lens was. At 10mm, I can stand just a few feet in front of a 13-story building, and get the whole thing in the picture, from the entrance to the top of the building.

As with all very-wide lenses, you have to be careful that you don't have people at the edges of the frame or too close to the lens, or they will appear very distorted when taking pictures at 10mm. Also note that a wide angle lens is not easy to use at first to create compelling images, as it's very easy to include too much clutter in your compositions.

PROS
- optical quality is excellent (deserves an "L" lens designation)
- uses the higher quality ring-type USM focusing
- minimum focusing distance is very close
- surprisingly lightweight
- very flare-resistant even without hood
- the only option for EOS digital cameras (Rebel, Rebel XT, 20D) to get true wide angle shots due to the smaller APS-C sensor in those cameras.

CONS
- It's expensive! But at least it is cheaper than a year ago.
- The lens is a little soft in the corners at 10mm, but is very sharp at 12mm and up.
- Canon has not formally committed to how long they will continue to make cameras and lenses using the EF-S system.
- The lens currently only works on the lower-end dSLR cameras -- the 10D, 1D, 1Ds, and 5D cameras cannot use this lens.
- The hood is not included with this lens, but it's such as ugly hood and the lens doesn't have flare problems, so I don't really think it is necessary anyway.

In 5 years when you upgrade your camera, there is a possibility that it will not support this lens. This depends on what direction Canon goes in making camera sensors:
1) continue to make cameras that use the smaller APS-C sensor, and keep improving its density to support more and more resolution. This will help keep the dSLR cameras smaller and lighter, and will necessitate making EF-S lenses the standard.
2) make the sensors match the size of a frame of 35mm film. And at the same time increase the density to yield even more resolution. Right now sensors this big are very expensive to produce.

I now think that #2 is more likely to happen. All the other lenses out there are built for a 35mm-film-sized sensor, and now that Canon has released another full-frame camera (5D) at a lower price, I'm betting that in another few years the APS-C sensor will be practically obsolete. A 5D body and 16-35 or 17-40 lens will give you better results than a 20D with this lens, but the difference in price between the two setups is a few thousand dollars right now.

The 10-22 is an excellent lens, but it will probably not hold its value as well as the Canon 16-35 and 17-40 lenses. A slightly more affordable alternative is the Sigma 10-20mm, which sounds like it nearly equals the optical quality of this lens.

Great Lens
By hp
Bought this from a NYC camera store and was delivered to me 11/11/13. I put myself on the wait list the minute it was announced so I am likely one of the first to get this lens. I have had only a few days worth of shooting but will put my initial impressions here.

Pros:

1. Superb optics. I am not a pixel peeper but no issues at any focal length even wide open. The lens is very sharp with fair contrast. No significant distortion. Slight CA. No noticeable vignetting in real life situations. I am not sure if my EM-5 is correcting for this lens with software. I have not tried on Panasonic bodies. All of this at a constant f2.8 throughout the zoom.

2. Size. No comparison to larger format lenses with a constant 2.8 aperture in this focal range. Others manufacturers might make FF and APS-C cameras smaller and smaller but they cannot match the size of the m4/3 lenses.

3. Very useful zoom range for the average shooter. This can be the one lens you can have for the entire system. It covers semi-wide to semi-long, good for landscapes to portraits. You might want to get prime lenses for bigger aperture, smaller size or shallower DOF/subject isolation but with the newer m4/3 cameras that do well at higher ISO, this lens is fine even for night-time photography.

4. Fantastic build quality. Olympus 75mm might be a tad better made but it is close. I should know; I own most primes from Olympus and Panasonic and a few zooms. I have tried almost every lens made for the m4/3 system from any manufacturer from friends. The lens is solid with good heft but not too heavy. It has good dampened rings which are as good as any m43 lens although inferior to lenses from Leica or older (pre-digital) lenses from Nikon, Canon, Olympus, etc.

5. Looks fantastic. I know it has nothing to do with picture quality but if I was not into visually pleasing things, I would not be into photography in the first place.

6. Lens button. I love the fact I can assign DOF to this.

7. Auto focus/Snap focus. It's as fast and as quiet as any m4/3 lens used on my EM-5. The snap focus feature by pulling the focus ring back is something that gives Olympus a significant advantage over other manufacturers. Brilliant.

8. Included hood and lens pouch. I thought h*ll would freeze over before this would happen. It is getting colder recently.

9. On that topic; weather sealed.

Cons: (Minor)

1. The lens is not fully retracted at 12mm. It is actually fully retracted at 16mm. Thus, if you store with lens at 12mm, the front element is not completely against the body. I am not sure if this will impact durability over time as it is carried/stored.

2. The lens cap is huge (for Olympus). They needed to redesign the lens cap due to the hood but I feel it is too thick now.

3. The lens crashed my EM-5. The camera crashed when I first attached this lens. I am not sure if Olympus will issue a firmware update. It was interesting to find out the power lever on the EM-5 is software based; i.e., flipping it did not turn off the camera when it crashed.

4. Made in China, like iphones, ipads and most other electronics. I was hoping for Made in Japan.

Overall, a great lens and highly recommended for anyone looking for an all-around lens for the m43 system.

This is not your average Zoom!
By NyArtboy
Honestly, what can I say about this lens that hasn't been already said? This lens has become for many reviewers and bloggers, either the Lens of the year or runner up. This lens has pro level IQ, amazingly fast AF and one of the most useful all around focal range for photography today. at 2x crop factor on m4/3 it behaves like a 24-80mm. It has nice bokeh and good DOF (Depth-of-field) at 35mm+ (70mm) and very sharp at 12mm (24mm) wide angle. Some sites have said that the 12mm f2 lens is slightly sharper but to me it's negligible. PLUS you get all this IQ and focal range in a weatherproof package! Pair that up with the OM-D EM-1 and you have an adventure waiting to happen!

Another question that pops up frequently on blog pages and review sites is the question between this and the high quality prime lenses out there for the m4/3 format. My opinion (just my 2 cents) is if you plan on shooting on nice bright days and don't want the hassle of changing lenses, then bottom line, this is your lens. On sunny/bright days you will end up stopping down the prime lenses anyway so you will get just the same amazing results especially if you pair this with an Olympus OM-D that adds in-body 5-point IS and Chromatic fixes in the software for this specific lens.

On the other hand, if you like to shoot in low light, have no problem switching lenses, and generally want the ability to achieve the maximum DOF (depth of field) you can get on the m/43 format than stick with primes. Though to be fair, the bokeh and DOF is perfectly fine for my taste on this lens at the higher focal lengths. Plus it has an amazingly short focusing distance so you can get pretty darn close to your subject which will increase the DOF as well.

If you are concerned with price, you shouldn't be. A lens of this quality at this price is an amazing deal. Here is my cost comparison/value break down:

If you bought the 12mm F2 and 45mm F1.8 you would be $200 above the cost of this lens (all brand new) and only have 2 focal lengths.
The equivalent price in primes would be the 17mm f1.8 and the 45mm f1.8 but you lose the nice wide angle 12mm focal length and gain possibly the "best portrait lens" for m4/3 cameras with nice creamy bokeh and sharp IQ.
To me the ideal prime set is the 12mm f2, 25mm f1.4 (Panasonic) and 45mm f1.8 which puts you at roughly $1800 give or take.
A nice f2.8 combo would be this lens (12-40mm f2.8 Pro) and the 60mm f2.8 macro giving you a fully capable system of varied focal lengths plus macro and medium telephoto capabilities all for about $1400.

Pros:
Extremely Sharp IQ corner to corner
Super-fast AF (I think faster then my L series lens tbh)
The best and most versatile focal lengths for everyday photography
Ability to get very close to subjects. Just a few inches in fact
Large Aperture for decent bokeh and DOF
Weather-proof!
All metal construction
MF 'choke' design for quick switching to Manual Focus mode
Includes a customizable L-FN button on lens for additional functionality.

Cons:
Big and somewhat heavy (though half the size of lets say the Canon 24-70mm f.28 L) - The size doesn't bother me in the least I have to add. Makes the E-M1 look pretty awesome.
Tube Extends during Zooming (would have liked the elements to stay within the lens, thought this would probably double the price)
Not the smoothest zoom and focus ring on the market. The other primes I have are way smoother. In fact there is small 'tap-like vibrations' when zooming. After speaking with Olympus directly they informed me this is normal operation.
Loses almost 2 stops compared to the primes available today for m4/3 format cameras.

I'm happy to answer questions posted here in Amazon. Good luck!

Outstanding lens
By M. Gotts
I've owned Olympus' OM-D E-M5 camera body since Christmas 2012. Using the kit 12-50mm and the 40-150mm (24-100mm and 80-300mm 35mm equivalent) lenses I've had a fun year capturing photos. The camera has been everything I wanted it to be, with the exception of being just average tracking kids playing soccer.

But the 12-40mm f/2.8 lens takes the camera to a different level. I thought I was getting decent performance from the 12-50mm lens -- and I thought wrong. It's okay, for what it is, but it's slow (f/6.3 at 50mm) and just average in sharpness. With nothing to compare to, I didn't realize how it was holding back the E-M5's potential.

The 12-40 is truly top caliber. Sharp from corner to corner. Chromatic aberration cannot be found. Fast for extending the E-M5's low light capabilities at modest ISOs (I can gain nearly three stops from the 12-50mm in many situations). On the PC I'll zoom in on shots and be astonished by the crispness that simply didn't exist before.

Having never owned an expensive DSLR (I had a decent Nikon FE2 film body and some Vivitar Series I lenses in the 80's, however), I'd been lulled into thinking the images I was capturing were simply all that such a camera was capable of. The E-M5 is a very good micro four thirds body, after only the new E-M1. What difference could one lens make? Well, as it turns out, a great deal.

The 12-50mm has a smooth motor drive mode for video (which I rarely shoot) and a dedicated macro mode, which is nice. But the 12-40mm, while not being optimized for macro, turns out to be a fully capable macro lens as well, better than the 12-50, IMHO, because of its superior resolution and significantly faster performance and ability to isolate at f/2.8. The only step up for close up photography being to a dedicated macro lens. (And yes, I know that with regards to depth of field it is twice that of a full frame sensor. But f-stop is dimensionless, and with regards to light-gathering-per-sensor-size/exposure/ISO, f/2.8 is f/2.8 is f/2.8, whether it be APS, M43, full frame or a large format camera.)

The only thing I don't like is the price. $1,000 was a big chunk. But the way it has changed the performance of the E-M5 is truly revelatory. There really is a significant optical difference between a decent mainstream consumer lens and a pro level lens. The 12-40 lives on my camera now, and the 12-50 is going to end up on eBay.

If you've got the E-M5 or M1 and can afford it, this lens is a no brainer and will not dissappoint. Since the long end is only 80mm equivalent, I think even Lumix body owners can enjoy it's benefits despite not having the in-camera stabilization that Olympus bodies have.

My walkaround lens
By NutMac
The walkaround lens. This very topic leads to a heated discussion among DSLR photographers.

First, determine your budget, focal length, and aperture needs.

If you frequently find yourself zooming out to get everything in a frame, you will want a wide angle lens such as this. If you frequently find yourself zooming in, this is not the lens for you. On a full frame body such as Canon EOS 5D, this lens becomes ULTRA wide angle. On an APS-C crop body such as Digital Rebel XTi (which I used for this review), it becomes MEDIUM wide angle. But thanks to 1.6x crop factor, this lens expands to more usable 35mm equivalent focal length of 27 to 64mm.

Second, audition the lens if you can.

By definition, a walkaround lens should be relatively portable. At 1.1 lbs., Canon's EF 17-40mm f/4L USM is neither super light nor neck breakingly heavy. In fact, it weighs almost the same as Digital Rebel XTi -- really nice balance. The lens feels very solid with supreme build quality that only L-series lenses offer. Although this lens is weather proof and therefore sealed against liquid and dust, I strongly recommend getting a 77mm filter to protect the front lens element. With it, this lens is made to last.

In terms of looks and feel, it doesn't get much better. Its rubberized full-time inner focus manual ring USM focuses smoothly, quietly, and quickly. Since it's inner focus, the lens will not extend beyond its metal casing whether you zoom in or out. The focus window shows focusing distance from 0.28 meter (0.92 feet) to infinity. The focal length marker indicates 17, 20, 24, 28, 35, and 40mm. The lens exudes quality from tip to tip.

You may tolerate heavier lens or may not mind lesser build quality of cheaper lenses. A walkaround lens will be used very often, so make sure you will be comfortable with it.

This lens is famous for saturated color and deep contrast. Its images are simply stunning. At 17mm wide angle, barrel distortion is noticeable but relatively mild. From 24mm to 40mm, its images are distortion free and perfectly suited at capturing people.

Vignetting (corner darkness) is minimal with mild chroma abberrations (color shadows). At f/4 aperture, details become noticeably softer toward the edges. The center region is very sharp and at f/5.6, edges remain fairy sharp. Thanks to 7 diaphragm blades, this lens can produce very nice bokeh at 40mm (blur effects).

One of the most cited weaknesses is the f/4 aperture. In my experience, a bump in the ISO speed and steady hands are all you need to take well focused images indoor. On the other hand, if you are shooting with very little amount of light, you might wish for f/2.8 or image stabilizer. Although the difference between f/4 and f/2.8 is just 1 stop, my other lens, Canon EF 24-70mm f/2.8L USM (too heavy to be my walkaround lens) easily outperforms in such challenging situations. But by and large, I was not handicapped by the f/4 aperture.

Some of the main competitions (sorted by price):
- Sigma AF 17-70mm f/2.8-4.5 DC macro: Good zoom range with macro, and generally solid performance if you can get a good sample. It does suffer from a bit slow focus mechanism, soft corner, and chroma aberrations. Works only with EF-S mount.
- Sigma 18-50mm f/2.8 EX DC: Very good value for f/2.8 aperture, but Tamron's 17-50mm is a bit better lens overall. Works only with EF-S mount.
- Canon EF-S 17-85mm f/4-5.6 IS USM: This "traveler's lens" has a wider focal range than most wide angle lenses (widest among Canon) and is equipped with an image stabilizer. While it is a Jack of many trades, it is the master of none. Every lenses on this list will perform better at particular focal length. Then again, none of the lenses on this list has as wide focal range. It is famous for extreme barrel distortion at 17mm and chroma aberrations. Works only with EF-S mount.
- Tamron SP AF 17-50mm f/2.8 Di II LD Aspherical (IF): This is the most direct competitor. It takes sharper images with faster aperture while costing less. Both the build and focus mechanism are significantly worse, but should be good enough for many. Works only with EF-S mount.
- Canon EF-S 17-55mm f/2.8 IS USM: This is THE reference, if you can afford it. Its images have razor sharp details and great performance all around (minus vignetting, which is typical of EF-S lenses). The build quality is worse than L-series but still pretty good. Works only with EF-S mount. This is the best EF-S lens hands down.
- Canon EF 16-35mm f/2.8L USM: One of the most expensive wide angle zoom lenses. It's larger and heavier, but has f/2.8 aperture.

This is how Canon EF 17-40mm f/4 USM stacks up.

Pros:
- Among the very best build quality.
- Excellent, buttery smooth, super fast front-focus system.
- Top notch color and contrast. Very sharp center resolution.
- Almost non-existent vignetting, generally low distortion, and well controlled chroma abberrations.
- Ideal weight and size for walkaround purpose

Cons:
- Edge softness at f/4 aperture.
- Narrower focal length than most competing lenses.
- Slower than some third party lenses.

All in all, this is an excellent wide angle walkaround lens. It may not offer the most bang for the buck, but if you value full frame compatibility (EF lens mount) and excellent build quality, this is the default choice. This lens comes with a nice pouch and a lens hood. I find the hood to be somewhat ridiculously shaped and because the lens is resistant to flare, I do not use it often when shooting outdoor.

Versatility on the Cheap
By Genobambino
No one lens accomplishes every photographic objective. Canon makes each lens at every price point well-suited to various tasks, but with limitations that can only be overcome by graduating to the next higher priced but similar item. A case in point: the wide-angle zooms.

The 17-40mm f/4 is one of Canon's best deals in L-series glass. You have to spend twice as much to get a lens of similar quality, but just one stop faster. Does this make the more-expensive EF 16-35 f/2.8L a ripoff? Not for its own specific use: the extra stop gives you the speed to shoot in more indoor situations. Not all photographers need this. When indoors, we're often taking pictures of people, which are better suited to lengths around 50-100mm. To capture sweeping panoramas of parlors for Architectural Digest (or Coldwell Banker) the f/2.8 is the better lens and worth the step up in price, though in many cases you could use the f/4 lens with a tripod. All this means is that the f/2.8 is priced for professional specialists whereas the f/4 is for more general use. My bigger point is that Canon has its whole lineup positioned: the differences across lenses are specific and appropriately priced, which is good news for the consumer. It's hard to make a mistake buying homegrown Canon lenses, especially L-series lenses. You just have to figure out which set of two or three suits your range of uses.

The 17-40mm is a steal for people who need a walkaround lens for travel and outdoor photography. The shorter focal lengths of the zoom are great on a digital body, with nice reach and minimal distortion; just an ability to grab up landscape and wide situations end-to-end, even when standing close. The focal lengths around 40mm are tight enough for portraits and other local detail. Colors are strong and convincing; contrast deep and impactful. The lens itself is small enough and light enough to grab-and-go, but nicely machined, with solid fit and finish. It has an instantly recognizable profile, with the added bonus of the red ring.

This lens, plus a 70-200mm f/2.8 telescope and a nice fast fixed lens in the range betwixt are all you need. On vacation, and in most outdoor situations, the 17-40mm alone suffices. It makes a good first L-lens, and a staple in the arsenal.

Only decent in comparison to other L's
By Jesse R. Hunter
(I really want to give this lens 3.5 stars)

This review is written from the viewpoint of someone whom has used many L-class lenses, and as such will be a little harder on this piece of glass. If you've never used a Canon L lens and you purchase this one, I guarantee you'll be quite pleased with your purchase. But this review is really meant for those who own other L glass pieces and are looking into adding this one to their collection.

The good:

L glass tends to mean some heavy-weight glass, however this lens is surprisingly light and small. In fact, it is the smallest/lightest L zoom Canon makes. You find yourself more likely to take it to places where there may not be much of a projected photo opportunity or where there is a higher risk in damaged gear due to its unobtrusive size. It really is one of those few L lenses that you can casually walk around with and not garner much for attention.

As with all L-glass, this ones very solidly constructed. It has a simplicity of design that minimizes risk to moving parts from shock. It is well-balanced and just feels like a tight glass package.

The lens performs very well in color and contrast. Natural saturation is excellent, easily on par with the L expectation. The color and saturation of this lens sits somewhere between the 70-200mm f/2.8 IS and the 24-70mm f/2.8.

I initially thought that the zoom range would be constraining (a mere 23mm of range?), but in reality the lens is fairly versatile. This especially true on a 1.6 FOVCF body (20D, 30D, 350D, 400D, etc), where the range is more like that of a normal zoom, at the cost of the super-wide advantage. The lens handles pretty much all composition tasks except those of a telephoto or 1.0x macro. You won't be disappointed in the zoom versatility.

Price. This like, what, the second cheapest L lens available. For those whom are very accustomed to purchasing/collecting L lenses, anything under a thousand dollars really is considered on the cheap side. If this is your first L purchase, this lens or the 70-200mm F/4L are your places to start.

Flare. There's practically none.

Cons: (there's only one, but its a biggie)

Sharpness. This is by far my biggest qualm, and what makes me frown a little at this lens for its L designation. It's nowhere near that of other lenses. One of the biggest uses for this lens is landscape photography, where objects appear very distant and sharpness becomes crucial. 24mm at f/4 on this lens is easily less sharp than 24mm at f/2.8 (!) on the 24-70 f/2.8L. And as a little investigation will reveal, this probelm is also somewhat appearant on the 16-35mm f/2.8L (although it seems less pronounced). 100% crop comparisons of this lens to other lenses such as the 180mm f/3.5L is simply a joke.

Other:

This lens utilizes slight movement of the front element, so it is advised by pretty much everyone that a UV filter be purchased (77mm filter size). I add to that by saying: buy only the Multi-coated from B+W or Hoya if you're shooting digital. Yes, they're usually somewhere around eighty bucks, but spending forty on something that will bring you ghosting/contrast woes is not worth it.

The hood of this lens is hilarious. It's almost five inches wide and maybe an inch and a half tall. I simply don't use it (I can't geometrically see how it helps. I think it may be something of a feel-good-hood if you're not consiencious about flare.) The lens is less conspicuous without it and I really don't have a flare problem.

Conclusion

I'm really not satisfied with the sharpness issue. It seems at least somewhat appearant on almost all Canon's lenses below 35mm. (Except for the 24-70 and 24-105, which is odd). I think they're still working out their wide-angle formula. Appearantly, the new 17-55mm f/2.8 is supposed to be sharper than both the 17-40 and 16-35, so they are probably on the right track of improving the issue.

In the end, if you've never used L glass and are considering this one, buy it. You will be very pleased, I assure you. But if you own a good deal of L glass, you may want to hold off from this one and wait for Canon to improve their optics. You may find yourself like me, using other L pieces and only using this one when I absolutely have to.

Perfect. Did the job well!
By Ari
Ok, for any review stating that their glass had scratches, look again. I'm sure once in a blue moon there might be a scratch. However, I'm glad someone mentioned there are 3 layers of protective film to peel off the glass otherwise I would have missed it. There is a easy peel off film on each side of the replacement glass that extends past. But on the inside of the glass there is a 3rd film that is cut exactly the same size and is almost invisible unless you knew it was there. And yeah, until I took that last piece off I was freaking out that I got cheated into a shody product. But it was crystal perfect. The glass is not OEM but you can't tell at all. It's a pretty exact fit, maybe just a micro touch small at the edges but the difference would only be noticeable to the perfectionist's eye. From a distance of more than a foot, no one can tell. I'll trade that any day to having spider cracks all over my screen.

The tools work great. I didn't have any issues with mine melting. I used an embossing tool (which is pretty much a heat gun) but a hair dryer can be used too. Even though it shows in the picture, I completely overlooked that extra glue was included. Most glass replacements this isn't necessary because the OEM glue has plenty from the original build, but this was a nice perk nonetheless.

I'm not a gadgety person, I'm a house mom. Anyone can do this! If you watch a few different youtube tutorial videos to really get to know the details of the process, prepare all your tools to start and above all, TAKE. YOUR. TIME. to do it carefully, any novice can replace their galaxy 3 cracked screen. Take your battery/sim card/memory cards out before you start so they don't get damaged by the heat. It's is optional (but highly recommended) to take out your phone's circuitry too (many youtube vids on this too) to protect from heat damage.
Be aware though that if your digitizer (touch sensory)/LCD screen layer is damaged (you'll know this if your screen is rainbowy/black around the cracks or the picture is distorted), then you'll need buy a whole new LCD screen and glass replacement. You may want to send it for repair at that point unless you feel ambitious enough for the extra challenge.

Overall, mine came out perfect! I'll remember to put a protection case on this puppy this time. Screen protectors and ghost armor work great for dings and scratches. But my phone likes to cliff dive from any height to the floor.

This is awesome!
By mh9
My kid broke the glass on his Verizon SCH-I535 in a motorcycle crash. He is OK, the phone still works but the screen broke. I wasn't sure if this product would fit because the description said i9300, I747, T999 but not i535. After a bit of research that said it would fit, I gave it a try. Turns out, when you get the screen off, "i9300" is painted on the little ribbon cable for the Menu and Back buttons.

DISCLAIMER: This worked for me. Won't guarantee it will work for you. You are on your own, but it worked for me!

I can't stress this enough...research, patience, YouTube videos, patience, breathe, more videos, patience, more research and even more patience!

Youtube videos, heat gun, plastic tools only and patience while taking the screen off. Start at the ear piece end, not the home button. Careful when you get to the home button and don't break the ribbon cable that is glued to the back of the Menu and Back buttons. The ribbon cable will come off in one piece if you are careful.

Once I got the screen off, I wasn't exactly sure how to proceed because, as others have said, there were no instructions for the assembly. I sent a quick question to the help email address asking how to apply the adhesive strip, received an almost instant response (from a real person even!) and most of my worries were gone.

"After your old screen is removed you will notice a black gasket on the outer edge. Remove it completely. Clean with swab and alcohol. Take the clear liner off the back. Place sticky part to fit outline of the phone. Apply pressure to the edges. Remove the blue film leaving the black gasket / adhesive. Then complete the install of your new glass."

More patience while slowly, carefully using tweezers, alcohol, q tips (and I used Goo Gone) to get the black gasket and all the glue off. Watch out for the ear piece and home buttons. Mine popped off but I was able to position them back into place. I spent almost an hour getting all the glue off. There is a lot of glue all over the place! Some don't, but mine even had glue between the glass and the digitizer which will roll off when you gently rub it with your fingers. I thought I was done until I got a magnifying glass and saw even more glue! Time for even more patience!

Then I panicked when I saw all the alcohol residue fogging up the digitizer. I used Sprayway Glass Cleaner from Costco, a lint free cloth and a lot of deep breathing to clean that off. Panic averted.

Patience again when applying the new adhesive. Careful, that stuff is really sticky and sucks to anything it touches. Again, I carefully worked down from the ear piece towards the home button. I personally stopped before the home button and removed the blue film because I couldn't get the ribbon cable through the hole with the film in place. Stressful times again because the ribbon cable stuck to the adhesive but I was eventually able to get it all sorted.

Once the adhesive was in place, I used another lint free cloth to clean the digitizer without touching the adhesive. You know what it is like to have a spec of dust under your screen protector? Then you can just imagine how much it will bug you if there is dust between the screen and digitizer!

Ok. Clean? Ready? Time for the glass.

NOTE: As others have said, the glass is not scratched. There are three protective films on the glass. Two of them are very obvious, one on the front, one on the back. The third film on the back of the glass is very hard to see because it is closely cut to the shape of the glass and was difficult to get off.

Patience yet again! This time start at the home button end and carefully attach the ribbon cable to the menu and back buttons on the glass. This is important because they supply the light and response to the buttons when you press them. Be sure the home button and ear piece are in place, take another deep breath and carefully, patiently position the glass in place...because once that glass is in place, it ain't going anywhere...then press gently but firmly around the edges to anchor it.

Now, if you did it right, put the rest of your phone back together, power it up and pat yourself on the back for a job well done and saving yourself a lot of cash!

(FYI, really only minus 0.5 star for no instructions but they won't let me give 4.5 stars.)
