What is canon fd?

The Canon FD lens mount was introduced in 1971 and was the standard lens mount for Canon's manual focus SLR cameras until it was replaced by the EF mount in 1987. The FD mount featured a breech-lock system for attaching the lens to the camera body, which was unique at the time.

Canon FD lenses were known for their high optical quality, and a wide range of lenses were available in various focal lengths and apertures. Some popular FD lenses included the 50mm f/1.4, 85mm f/1.8, and 135mm f/2.8.

While the FD mount is no longer in production, many photographers still use FD lenses on modern digital cameras through the use of lens adapters. Adapting FD lenses to digital cameras allows photographers to take advantage of the unique rendering and character of these vintage lenses.

Overall, the Canon FD mount was an important part of Canon's history and legacy in the world of photography, and FD lenses are still highly regarded by many photographers today.
