EF 17-40mm f/4L USM



The greatest USP of the 17-40mm f/4L USM is its wide diagonal angle of view 104 ? (at 17mm) – 57 ? 30’ (at 40mm) making it perfectly suitable for landscape photography. The lens construction includes three aspherical lens elements and a Super-UD (Ultra-Low Dispersion) glass element. Full-time Manual focusing and ring-type USM (Ultra-Sonic Motor) rounds off the package for landscape photographers.


A new and affordable L-series ultra-wide-angle zoom lens that's ideal for both film and digital SLRs. Superior optics are assured by the use of three Aspherical lens elements, in addition to a Super UD (Ultra-low Dispersion) glass element. Optical coatings are optimized for use with digital cameras. This lens focuses as close as 11 inches (0.28m), and offers both Canon's full-time manual focus and a powerful ring-type USM for fast and silent AF. It has a constant f/4 maximum aperture, and offers the choice of screw-in 77mm filters or a holder in the rear of the lens for up to three gel filters. Finally, it offers weather-resistant construction similar to other high-end L-series lenses.
