Canon EF Lenses manual Getting Everything, EF 16-35mm f/2.8L USM EF 17-40mm f/4L USM

Getting Everything In

If your mind’s eye calls for a very wide shot, how about one of the three ultra-wide zoom lenses? The zoom range of these lenses suits the vast majority of wide-angle shots you will ever take. Or, try a standard zoom lens with a focal length from wide to telephoto to get the most out of your camera.

ULTRA-WIDE ZOOM LENSES

EF 17-40mmf/4L USM •f/8 •1/250 sec.

EF 16-35mm f/2.8L USM •f/2.8 •2 sec.

EF 16-35mm f/2.8L USM EF 17-40mm f/4L USM EF 20-35mm f/3.5-4.5 USM

A superb lens that covers nearly every professional wide-angle task. Out- standing optical performance comes from three Aspherical lens elements, and (for the first time ever in an EF wide-angle zoom lens) two Ultra-low Dispersion UD elements. Weather- resistant construction, a rear gel filter holder, close-focusing to 11 inches (0.28m), and a circular diaphragm are among its many highlights.

About half the price of the 16-35 f/2.8 lens, this L-series lens has an entirely new optical design with three Aspherical elements and a Super UD-glass element. The combination provides superb contrast and sharpness, even at the widest settings. It’s ideal for both film and digital SLRs, and features the same weather-resistant design, rear gel filter holder, and high-speed Ultrasonic Motor as the EF 16-35mm lens.

A superior performance ultra-wide- angle zoom lens, covering the entire range of popular wide-angle focal lengths. A ring-type USM and an inner focus design provide fast and silent AF, along with full-time manual focus override. Priced within the range of serious photo enthusiasts, it’s a great all-around choice.
