The EF17-40mm f/4L USM is an ultra wide angle Canon EF zoom lens meant for professional and high amateur SLR EOS camera users.

While it is an excellent lens when used with an analogue SLR camera, the EF17-40mm f/4L USM is especially well suited for digital SLR cameras with an imaging sensor size smaller than the 35mm format. Indeed on such digital SLR cameras these focal lengths can give an angle of view approximately equivalent to that of a 28-70mm lens used on a 35mm camera, which makes it the ideal standard zoom lens.

The EF17-40mm f/4L USM has 12 lens elements arranged in 9 groups. Super Spectra Coating on the elements ensures excellent color balance and minimizes ghosting and flare. To provide superb image quality over a 17-40mm zoom range the lens uses three aspheric elements of two different types, while Super UD (Ultra-low Dispersion) glass is used to prevent the chromatic aberrations that often can degrade the subject edge clarity.

Minimum focusing distance is just 28mm throughout the entire zoom range. The Auto-focus works silently and quickly thanks to a fast central processing unit with an improved AF algorithm. You can override AF mode with manual focus should you wish. Controlled by an electromagnetic diaphragm, the EF17-40mm f/4L USM's circular aperture can achieve a more attractive appearance to out of focus background areas in a picture. The front of the lens does not rotate as you focus. This means, for example, that polarizing filters still function effectively as you zoom in and out. At the rear of the lens there's a drop-in gelatin filter holder. Highly resistant to moisture and dust, the EF17-40mm f/4L USM is ideally suited for use in harsh environments. Environment friendly lead-free glass is used throughout its construction.
Canon EF wide-angle zoom lens 17-40mm is rated 4.6 out of 5 by 60.
Rated 4 out of 5 by from Affordable L Glass Lens Great value L glass lens. I got this lens to upgrade from my kit lens for my Canon Rebel T5. Just tested this lens out by taking exhibit hall and cosplay photos at San Diego Comic Con. Pros: The lens is relatively small and light weight, which was great for carrying around all day, and the color is fantastic. Cons: This lens does not have image stabilization and is definitely not as sharp at the widest aperture (f4), which means taking indoor photos with lower light results in very soft focus photos. Looking forward to trying this lens out for some landscape and travel photography in future!

Rated 5 out of 5 by from Great Lightweight lens I was looking for something that would be a nice lightweight carry lens for my 7d. I bought this right before a trip to the Biltmore house and it fit my needs perfectly and I was able to get some really great shots. It is much sharper then the 18-135 kit lens. I really have no complaints about the lens at all.

Rated 4 out of 5 by from Great ultra wide angle lens Just received the lens yesterday and took it out and shot some landscape photo's. I shot in jpeg and RAW and the pictures turned out great. The lens was attached to my 6D MII. Being the lens has been on the market for a very long time it still holds it's own. Yes there are some down sides to the lens and you can see vidoe's about the lens on YouTub. But the lens was within my budget and does what I want it to do.

Rated 5 out of 5 by from Great value for the buck! Was looking for a used 16-35 mm zoom for shooting landscapes and came across this lens. It may not be as fast but it is as sharp and just as reliable. Depending on your needs, this is an excellent lens either as your go-to lens or as a back-up.

Rated 5 out of 5 by from Razor sharp shots, fast auto focus This is an outstanding workhorse lens. Images come out crystal clear, and the build is everything you expect from an "L" series lens. I couldn't be happier with it.
