Canon EF 24mm f/2.8 - Canon EF Mount

The Canon EF 24mm f/2.8 is a classic wide-angle prime lens offering a broad field of view on full-frame cameras and a 38mm equivalent on APS-C bodies. It features a simple five-group optical design and a compact form factor. While it lacks the modern USM motor, its AFD motor provides reliable autofocus for landscape and street photography where a small, unobtrusive lens is required. Used examples should be checked for the condition of the AFD motor, which is louder than modern equivalents but should still be responsive. We look for any signs of internal dust or haze that could affect contrast. SDS tests the aperture diaphragm to ensure it remains snappy, as older EF primes can occasionally develop sticky blades. The mount should be checked for consistent electronic communication with the camera body.
