I use this lens with the canon 5D MK III. It replaces the 16-35mm f2.8L. I like the 17-40 because it's small, light, and less expensive compared to the 16-35. It uses a 77mm filter like my other Canon zooms. The f4 is relatively fast, and meets my needs for an ultra wide angle on a full frame sensor. There are compromises with the lens, compred to the 16-35, but I have not found any faults with it.

I've just gotten started with it, but I'm using this lens on a 5DmkII. It's easily my widest lens, and is quite wide on the 5D. I've never used the 16-35 or the 14mm. While it's not exactly what I would call a cheap lens, it is cheap for an L lens, and so I would expect some compromises to have been made. While I've not done any sort of side by side comparison, I would say it's not the sharpest lens, particularly at the edges, and it does have some vignetting. This seems to be the case even when stopped down and zoomed, although these issues are probably worst at 17mm at f4.On the upside, I do like the metal construction and weather sealing of an L lens. It opens up to f4 regardless of focal length, which is fast enough to use the precision focusing screen on the 5DmkII (it's visibly darker than the normal screen, but usable). I'm not unhappy with the distortion it produces. Most importantly, it's a seriously wide, Canon L lens for only [$] The 16-35 and the 14 are both twice as expensive.

    Comments about Canon EF 17-40mm f/4L USM Lens:

    I take mainly landscape photos and coming from my kit EF-S 18-135 and EF 50 1.8 this lens is incredible. This is possibly the best bang for the buck Canon offers. It is an L series lens that is good quality glass for under $. The only drawback is its easy to bump the zoom adjustment if you aren't careful.

      Comments about Canon EF 17-40mm f/4L USM Lens:

      I have a Canon 6D and a 50mm f/1.4. Both are a great combo. However I felt some limitation with my 50mm, especially when travelling or being indoors: I had a hard time to get buildings into the frame or to get everyone on a picture at a dining table. Therefore I wanted a wide-angle. I first thought about a prime lens again, but then I figured that a zoom lens would give me more options. Being used to my super wide aperture of 1.4, I was worried about the f/4. During the weekend I finally had the chance to try out the lens and I don't regret a thing: I was able to take nice picture from a sports event and last night I took my first cooking photos in our tiny kitchen. The rather small aperture hasn't been a problem so far.
      At 17mm the picture is of course distorted as many may have mentioned, but this is fine for me since it is super wide-angle.
      This lens is a good counterpart to my 50mm.

      I use this to take pictures in the Florida Everglades. I love the sharp images and the fact that the zoom is internal and doesn't extend the actual lens when zooming in/out. I don't like the hood too much, but aside from that, this is one fantastic lens. Love it! I'm very happy I bought it!

          Comments about Canon EF 17-40mm f/4L USM Lens:

          Bought with an EOS 6D at B&H's superstore. Wanted a quality wide angle zoom and liked the 17 to 40mm range. Had to be an L Series lens - I like the quality. Also needed an EF lens to cover the 6D's full-frame sensor. Salesman at B&H showed me a variety of lens and body combinations. After choosing the 6D and trying the 17-40 f/4.0 in-store, I was sold. I used it that night to shoot the Manhattan Skyline and night shots of and on the Brooklyn Bridge. From the Brooklyn waterfront, at 17mm I was able to capture the full Manhattan Skyline from the Statute of Liberty to the Brooklyn Bridge, then zoomed in on just Manhattan. Highly useful range. Zoom action was smooth and clean as I expected from an L series lens. It is surprisingly lightweight yet feels solid. I shot on a tripod and got great images. Only negative was not having the money to buy the faster 16-35mm f/2.8L, but I very happy with this lens and the price.

              Comments about Canon EF 17-40mm f/4L USM Lens:

              Good lens and a good value, lightweight and portable. If you can afford the upgrade, definitely worth the price to get the 16-35mm f/4 IS. If I had known it was coming out less than a year after I bought the 17-40 I would have waited. It is definitely much sharper. The 17-40 served me very well though over the past year. It's a good lens and I love how it is nice and light and small. Great for backpacking.

              This is a great L series lens. The images are very sharp even with wide open aperture. Lack of IS is noticeable when shooting indoor handheld at low light. But I got this lens for my landscape photography and IS is not required as I'm shooting with Tripod. Barrel distortion is quite big at the widest focal length but can be corrected somewhat in Photoshop/Light Room, just need to avoid putting people at the edge while shooting 17mm. Overall this is a great lens to have for the landscape photography compared to the pricier brother 16-35mm f/2.8.

Gives me perfect range to do wide that covers almost any room, and go in for a waist up shot if needed, as well as just sufficient for establishing shots / exterior shots. Almost a default lens. Great L quality, that's a given.

                      Comments about Canon EF 17-40mm f/4L USM Lens:

                      I use this lens for weddings and production shoots on a 5D mark iii. The resolution is outstanding. It's just wide enough to make walking motions very smooth, but not as wide to make everything look "bent." You don't necessarily get the manipulation as you would with an 8mm or so, which I prefer.

                      This lens is also easy to focus with manual focus, which I also like using since I'm moving around a lot, or at least my subjects are.

                      The only thing that I would change about this lens is that it doesn't have a stabilizer. But, like I said, even without that feature you can make video look very smooth, even if you're just doing a crab walk.

                      I have shot a bit of still work with this lens as well, and I have loved the way pictures turn out. Everything is crisp and in focus.

                      Also, I've noticed that this lens has been great in low light situations. A lot of reception halls that I've been in are dim to set the mood, but the lens has always been able to handle it.

                          This is a lens I've wanted for some time.

                          This will be used for a wide variety of things. I'm beginning to get into high-end real estate photography, and this lens is perfect. It's also great for landscapes (I think that's a given) and, as I've come to discover, maritime photography. Just like real estate, the wide angle lends itself well to shooting boat interiors.

                          I can't imagine being happier with a lens than I am with this one...
