Wide-angle lenses let you capture more of the image by broadening the angle of view and increasing the depth of field, thereby bringing more of the area into focus. The lenses also provide a unique perspective by expanding the apparent distance between the foreground and the background. This Canon 20mm f/2.8 is no exception, with such additional features as a floating rear focusing system with an Ultra Sonic Motor (USM), a 0.8-foot close focusing distance, and a 94-degree diagonal angle of view.
