Canon Lens EF 20mm f/2.8 USM

The optical performance, fast f/2.8 speed and ultra-wide-angle coverage make this a great choice for many applications, like interiors, scenics, travel and photojournalism. It uses a “floating” optical system for excellent sharpness even at its minimum focusing distance of under 10 inches (0.25m), and with a ring-type USM and full-time manual focusing capability, offers the speed and handling pros expect.

Ultra-wide-angle lens for serious applications. Easy to hold and carry at 405g. Floating rear focusing system. Sharp images are obtained at all subject distances.
