Canon FD Reversing Rings

Allows you to reverse mount a Canon FD lens. With earlier breech lock type lenses, you need to move the aperture lever which protrudes at the back of the lens to the end of its travel, where it should click into place allowing you to set the aperture manually. Later bayonet type lenses will have to be used at fixed aperture without additional items. Contact us for details. Use SRB~Griturn SPACER RINGS between the camera and the ring to increase magnification. Use SRB~Griturn STEPPING RINGS to use with a lens having another size filter thread. These adaptors allow ANY lens with the appropriate filter thread to be reverse mounted.
