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.

        This is what I use for interiors and landscape. Best if focused manually. I have a 5DIII and use magic lantern which gives you focus peaking (plus a lot more) on the 5DIII and that makes critical focus easy to achieve. The lens produces very good colors and detail if used at f/ or f/11 especially. Worth every cent.

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

          I use this lens as an all-purpose lens, since I have an APS-C body (equivalent FoV of 25.2-64mm). It is very light, so makes a perfect walk-around lens.

          This is my first L-series lens and it feels great! It feels solid, the zoom and focus rings move very smoothly. The autofocus is fast and accurate and the image quality is great. Images are sharp and, at least on a cropped APS-C sensor, show little vignetting.

          The only thing I don't like about it is the lens hood: it is very wide and short, so in addition to be of dubious use, it is not straightforward to store the lens with it on reverse (I have to remove it and store it separately).

                I've owned both the 16-35/2.8 and this lens. If you don't need the extra aperture of the 16-35, the 17-40 is a much better value. I use it on a full-frame camera (1D-X) and couldn't be more pleased with it. I use it primarily for sports (Basketball) and landscapes.

                  No wonder this lens is much loved. It's a piece of glass that handles light, and color along the full range without much if any flare, or chromatic aberration.

                    I felt the need to leave a review, which I don't do that often. This lens, a couple stops closed, is fantastic. I started shooting architecture/commercial real estate using a 24mm-105mm and this lens was a huge upgrade and much wider. Even though 24 to 17 only seems like a 7mm jump, it's not the same as going from 193 to 200, 7mm at the wide end makes a big difference. You can see my architecutral photography folow here http://www.joshpabstphoto.com/ and most of the shots were taken on this lens. I'm now looking into getting the 17 TSE (tilt shift), but this is a great lens to get started in street, real estate, ect.. I love. I don't do a lot of landscape, but I have no doubt that on a tripod and closed down a little, this lens would be great. It does have significant barrel distortion but it's fixed with the click of a button in lightroom.

                      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!

                            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.

                              All my glass is L series because I want super sharp images. I bought this one for interior shots for real estate agents. It works as it should...

                                Wide and very sharp on my 6d. I use this lens everyday. I shoot a lot of real estate photography and it works great with minimal distortion. This is my second one, I broke my other one and didnt last long without it. Also great for shooting landscape. Love it.
