Fotodiox Pro Lens Adapter Canon FD to Canon EOS Camera

The Fotodiox Pro Lens Adapter for Canon FD to Canon EOS is a third-party mount adapter designed to let photographers use their manual-focus Canon FD-mount lenses on Canon EOS (EF-mount) DSLR camera bodies. It’s aimed at photographers who own legacy FD-mount lenses from Canon’s film SLR era and want to continue using them on Canon’s later autofocus EOS DSLR system.

Because the FD and EF mounts have different flange focal distances and are not natively electronically or optically compatible, this adapter includes a corrective lens element to allow the FD lens to achieve infinity focus on an EOS body, since a simple mechanical spacer alone would not permit focusing to infinity given the flange distance difference between the two systems. Photographers should be aware that adapters using a corrective optical element can introduce some tradeoff in image quality, such as a slight softening or optical degradation, compared to using the lens on its native FD-mount body, a common characteristic of adapters bridging mount systems with an optical element rather than a simple mechanical pass-through.

As a fully manual adapter, it does not support autofocus, automatic aperture control, or any electronic communication between the lens and camera body, meaning photographers must manually focus and, in most cases, manually stop down the aperture using the lens’s own aperture ring, since FD lenses were not designed to communicate electronically with EOS bodies. Exposure metering behavior will depend on the specific EOS camera body used, and photographers should confirm how their particular body handles metering with a fully manual, non-electronic lens attached.

Build quality typically includes a metal mount on the camera side for a secure, precise connection to the EOS body, consistent with the construction expected of a mount adapter handling the physical load of an attached lens. Because this adapter is designed specifically to bridge the FD-to-EOS mount gap, it is intended for photographers with existing Canon FD-mount lenses rather than as a general-purpose adapter for other lens systems.
