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:

    Great lens for landscape and architectural photography. A little soft at edges if you are a pixel peeper.
    Has a nice internal focus mechanism, appears weather resistant (I have not taken mine out in the rain)
    I did not notice any barrel distortion, I had rented a 16-35 f2.8 and it had noticeable distortion at 16 mm.

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

      Having shoot with EF 17-40mm f/4L for several months, I can say that this zoom works well as a walkabout landscape lens on a 6D, if I am not planning on swapping lenses. On this body, it can see really wide, although I rarely keep anything taken beyond 24mm, because of the optical distortions. At the 40mm end, this lens take great group portraits. The IQ is excellent. A range provided by zoom is perfect for an APS-C body, which was a decisive factor for me.

        If you shoot landscapes and need a wide angle lens you really can't go wrong with this lens. It provides wonderful optics, it has 77mm front threads for filters. I am extremely happy with this lens.

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

          Purchased this lens to use with my Canon 6D and while it may not have that last 1mm of focal width or the step up quality of the f/2.8, for the relative price, it's pretty spectacular.

          I mostly shoot still landscape for fun and my shots with this lens have been some of my best ever especially around low light / night and long exposures.

          The range is notably wider than your typical kit lens, stabilization works well, the detail solid though a little soft outside (or maybe it's just my shooting), and it's easy to adjust. Much of my use is on long hikes and in very cold places and everything has held up beautifully for that though there is enough of a lip on the front of the lens for small particles to catch under and it does fog up quickly.

            Having 17mm and 35mm together was exciting to me. And mostly it will be used for wide shots so f4 was more than enough for me.

              I saw this lens on the B&H website and ordered it not realizing it was not stabilized. At 74 years old, I am not as steady as I used to be so returned it. Those images (see attached) I took with the camera braced were very nice. It's a winner for the not so shaky or tripod crowd!!!!

                This lens performs very well for large view sweeping landscape work and also very well for close-up imaging in rather confined spaces such as in a cavern. The f/4 aperture and L series quality glass and optics make this one of my best lenses. There is nothing that I don't like about it! It is not f/2.8 nor does it have IS; but, since I shoot with it almost always on a tripod, those are features I don't really need and am glad I didn't pay for. For me, this is a great lens and I am really pleased with it.

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

                Canon tries to give the consumer a chance to own a relatively inexpensive "L" lens with this one but they also take away some important features in order to make the lens more affordable...

                There is no IS (image stabilization)
                There is a 4.0 fixed aperture opening where it should have been a 2.8 fixed.

                Its basically a consumer lens with a red stripe and an "L"printed on it.

                  My wife and I have shared one of these for a few years. When it came time to buy a second wide angle we looked at other options but finally opted for a second of the 17-40.
                  This lens covers a nice range of angle of view and does it at a reasonable price.

I was using it on a tripod with just the ambient light with my 5D and got some great shot. My other use has been landscape. It allowed me to take picture of the huge live oaks in Florida without cutting off the limbs. I would recommend it to a friend.

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

                    On a full-frame camera, anything shot at 17-22mm is basically unusable. Faces, bodies, buildings, etc. at the edges of these photos will be completely deformed.

                    Some people will suggest that if you shoot the "right" way, you won't have this problem. But that is basically just saying it doesn't work for most shots. It only works for very few shots, which defeats the whole purpose of having a wide angle lens like this.

                    22-40mm it will produce some really sharp images.

                    Otherwise you would be better off buying a lower end crop sensor camera and a Tokina 11-16mm (which I've owned in the past and works very well) or maybe saving up for the expensive Canon 16-35m (which I've never owned and may possibly have similar problems).

                      Just upgraded from crop sensor to full frame and neede a lens for landscapes primarily. This lens is perfect for that. Typical "L" series glass. Focus is fast and sharp. Almost always use tripod for landscapes so the f4 is no problem. This lens is all that I expected!

                        I use this lens with a Canon 6D camera. So far, I've shot only about 200 still photos and about 15 video clips with this lens. I've used both AF and MF in shooting my still photos. All the still photos and the videos I've taken look sharp to me, and that's all that matters to me. I'm not very knowlegeable about photography, so I do not know of anything that's not great about this lens.

                        I think this is a good wide angle for the price. The only thing I don't really like is the shadows around the edges, I understand it's because of the wide angle, but my 10-18mm for canon 70d doesn't produce that shadow.

                        I shoot a lot of large indoor spaces, so the 17-40 is great at capturing my entire (huge) subjects with great clarity and without much distortion. I've heard mixed reviews about this lens in low light but have yet to experience that problem. This lens is so versatile and takes crisp, beautiful photos. It's a little big heavy but not enough to offset the benefits. I'm so glad I got it.

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

                          In 2013 my trusty Rebel XTi was wearing out with a sticking shutter. Very happy with Canon I decided to take a step up to the 60D, I also treated myself to my first "L" series lens, the 17-40mm f/4. I was never happy with the lens; I blamed it on the lack of IS. The 60D actually took better photos using the "S" series 18-135 f/4 IS. This year I decided to add another lens to my collection, as a read a ton of reviews of different lenses I realized people that use full frames cameras (such as 5D & 6D) had much more favorable reviews of "L" series lenses than folks that use crop-censor cameras (such as 60D). After a lot of research, I decided to buy a 5D MarkIII full-frame camera. This 17-40mm lens is 100% better than it was on the 60D. The field of view is much wider and 100% sharp and crisp. Even without IS everything is sharp while taking hand held shots of moving subjects. I've since bought a couple more "L" series lenses with outstanding results. I now love these "L" lenses, especially the 17-40mm! My advice is spend the extra money and buy a full-frame camera! Paired with "L" series lenses the photos are outstanding, even at night I can take hand held shots that turn out clear!

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

                            I find this lens is extremely useful for video production, especially for weddings when you are in a tight room and can't back up anymore. The f/4 is a little limiting, but I hardly ever am using that while I'm free hand holding the camera due to tight focus. The controls are smooth and I haven't noticed any distortion in the videos.

                              It's canon L lens, so the construction is pretty good and solid. I used it with 6D for wedding and landscape photography.
                              No complain here.
