The Vello Canon FD Mount Lens to Micro Four Thirds Camera Adapter allows you to mount any Canon FD lens, including a breech-lock or bayonet mount, to a Micro Four Thirds camera body. The all-metal adapter is designed to fit the lens securely, yet can still be removed easily when not needed. Additionally, it features an aperture lock.
Automatic aperture and AE metering will be disabled by the lens adapter as there will be no mechanical linkage between camera body and lens. You will need to set exposures manually or meter in aperture priority mode. The lens will retain its ability to focus to infinity.
