Add to Favorite Sellers. 17-40mm ultra-wide-angle zoom lens with f/4 maximum aperture for Canon SLR cameras. 3 aspherical lens elements and super UD glass element create superior optics in all conditions. Superb optical performance throughout the zoom range. Fastest AF speed within its class (same as the EF16-35 f/2.8L USM). Highly dust and moisture resistant. 28cm minimum focusing distance at all focal lengths as of January 2003. Ultra wide lens for analogue EOS SLR cameras 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. Standard zoom lens for digital EOS SLR cameras 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. Superior optical performance The EF17-40mm f/4L USM has 12 lens elements arranged in 9 groups. Super Spectra Coating on the elements ensures excellent colour balance and minimises 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. Extensive set of high-end features 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 polarising 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. Maximum aperture: 1:4. Lens construction: 12 elements in 9 groups. Diagonal angle of view: 104 to 57 degrees (at 30 feet).

A new and affordable L-series ultra-wide-angle zoom lens that’s ideal for both film and digital SLRs.
