The bayonet joint of Canon FD assumed mechanical communication of the camera and lens (as, for example, still at Nikon). Were transferred the established value of a diaphragm and illumination of a lens. The bayonet joint of Canon EF was developed in 1987 and had only electric connection.

Canon FD: 42mm
Canon EF: 44mm

And therefore it is simple and easy to put a lens with Canon FD bayonet joint on the camera with a bayonet joint of Canon EF it won’t turn out.
It is possible to find easily a lot of Canon FD adapters — Canon EF with a lens. At once forget about them. They are very primitive devices and strongly influence quality of a picture. Any meaning of purchase of the lens Canon FD is lost.
You need adapters without a lens.
On Internet open spaces you can find Canon FD adapters without the lens – Canon EF by Canadian firm EDMIKA.
