Description

The Canon EF 20mm F2.8 USM is a full-frame ultra-wide-angle prime lens introduced in 1992. Its 94° diagonal angle of view provides a broad perspective suited to landscapes, architecture, interiors, travel, and environmental photography.

The F2.8 maximum aperture offers useful flexibility in lower-light situations while maintaining a relatively compact design for a full-frame 20mm lens. Its 25cm minimum focusing distance also allows photographers to work close to subjects while emphasizing the surrounding environment.

The optical design uses 11 elements in 9 groups with a floating rear-focusing system. Canon's ring-type USM provides fast and quiet autofocus, while full-time manual focus allows manual adjustment without switching out of AF mode.

With its fixed 20mm focal length, compact 405g construction, and Canon EF compatibility, the lens remains a practical choice for photographers looking for a classic ultra-wide prime for both film and full-frame digital EOS cameras.
