Canon 17-40mm F/4 L USM EF Mount Lens {77} Description


The Canon EF 17-40mm f/4 L USM is a professional grade wide angle zoom lens. With the ability to go from normal to ultra wide angle focal lengths without changing lenses it's a great tool for for architectural, landscape, & street photographers.

This lens features a plastic body, meaning its lightweight and easy to carry around for long periods of time. The optics are very good despite the fact that it's a zoom. It also features a constant aperture of f/4 which is more than enough for daylight shooting. It also features Canon's USM (Ultra Sonic Motor) drive, which focuses quickly and makes the lens nearly silent.

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. It offers weather-resistant construction similar to other high-end L-series lenses.
