Olympus OM Reversing Rings

Allows you to reverse mount an Olympus OM lens. In order to adjust the diaphragm manually, you will need to press the depth of field preview button on the lens. Try folding a small wedge of paper, position it over the button, and use a tight elastic band to keep the button pressed in.  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.
