Product Highlights
  • EF Mount L-Series Lens
  • Aperture Range: f/4-22
  • Three Aspherical Elements, One Super UD
  • Ultrasonic Autofocus Motor
  • Manual Focus Override
  • Water and Dust Resistant
  • Internal Zooming and Focusing
  • Truly Circular Diaphragm
  • 77mm Front Filter Diameter
  • Rear Holder for Three Gel Filters

The EF 17-40mm f/4L USM Lens from Canon is a high quality "L" series wide angle zoom lens for full frame and APS-C size DSLR cameras. It combines one high-precision molded glass aspherical element and two replica aspherical lenses to achieve the extended zoom range, while also correcting for common aberrations that arise during zooming. A Super UD (Ultra-low Dispersion) glass element minimizes the chromatic aberration of magnification which tends to occur with wide-angle lenses, to help eliminate color bleed along the edges of the subject and achieve high image contrast and resolution.

The lens' minimum focusing distance is just 11" (28cm) throughout its entire range of focal lengths, which makes it very useful for close-up work. All of the focusing and zooming action is done internally, with no changes in the size of the lens. Its ultrasonic autofocus motor enables smooth and silent autofocus action and manual focus override in One Shot AF mode allows precise manual focusing without switching into MF mode.

It only uses lead-free optics to help the environment, and features a circular diaphragm for improved background blur. The housing is water and dust resistant to help ensure reliable performance for both professionals and enthusiasts. Like many "L" lenses, it uses 77mm filters, but also has a rear gelatin filter slot behind the lens mount that can hold three gel filters.

This lens is a Canon 'EF' series lens, indicating it is for use with full-frame cameras. However, it also works with APS-C format DSLRs and offers a 35mm focal length equivalence of 27-64mm, making it an ideal medium-aperture standard zoom lens.

A super wide-angle zoom lens for full-frame DSLR and 35mm film cameras that offers a 27-64mm focal length equivalent when used on APS-c size sensors.
Uses three aspherical lens elements and Canon Super UD ultra-low dispersion glass for reduced aberrations and overall sharp, high contrast imaging
An ultrasonic autofocus motor provides fast, smooth and quiet AF action, particularly important when shooting video.
Manual focus override enables precise manual focusing even when in One Shot AF mode.
Internal zooming and focusing systems
As a Canon "L" series lens it provides professional levels of moisture and dust resistance.
Circular aperture diaphragm for better, more natural looking background blurring
Accepts 77mm filters, as well as gelatin filters at the rear of the lens.

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:

      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!!

            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.

I bought this lens for my trip to Antelope Canyon and Arches National Park in a couple of months. I use this lens with my Canon T3i. Mostly do landscape photos.

                Needed a proper wide zoom for my 6D. This one fit the bill just fine. Sharp where it counts. Have used it already on TV pilots and commercials. I have been using the t2i's kit 18-55mm for 2.5 years. Learned all the quirks of it and then switching over to the 17-40 was like going from an economy to a sports car.

                      Another quality lens from Canon added to my collection. You can't beat the "L" series lenses, sharp and well built. Looks like my new favorite lens.

                        I needed a wider lens than my 24-70 for various situations (landscape, architecture etc...) so I purchased this 17-40 f/4. It is a compact, light, half the price of the faster 16-35 and an overall great lens. I was surprised how much I enjoyed using it right from the start. It was essential for capturing the beautiful landscape in Iceland. I do not have any complaints about this lens at the moment.

                          I needed a wide angle lens for my full frame camera, but didn't want to spend a lot of money. The 17-40mm f/4L is a great lens at an affordable price. It's solid, sharp, and just wide enough.
