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.

    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.

    Good lens

    By Dan

    from San Diego

    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.

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

    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.

            Use it with C-100, 7D and 5D, along with 24-105 L and 70-200 L. Love it. Biting my elbows for not buying it long time ago. 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.

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

                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...

                      This a pro lens that delivers great quality crispy sharp images, has a consistent output with a strong construction as a Canon L series should be and if that wasn't enough for a high end piece of glass although is not as fast as the 16-35 2.8L the price is right!

                      An add to your arsenal that becomes very helpful and versatile when used with a APS-C sensor size camera

                      I bought it from B&H since it first came out and and still after all these years of using it a lot, this little work horse amazes me like there is no tomorrow knowing there is.

                      Trust me, you will not be disappointed!!

                          This is a great wide focus for my house interiors in order to get wall to wall shots.
                          I do have to be careful not to stand too close to an item, or it will be distorted.

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

                            Bought the lens to complement my Canon 6D. My first full frame camera - I wanted the opportunity to photograph breathtaking landscapes, e.g. Grand Canyon, Mojave Desert, etc.

                            Test shots have been great. I have also used it for some night sky photography with decent results.
