$40 · M42 to M39 (Pentax Thread to Leica Thread adaptor)

M39 to M42 adaptor allows you to mount a M39 threaded lens onto any M42 threaded camera body. Due to the difference between the position of the lens to the film plane, you can not focus on infinity with this adaptor. It is intended to be used for close-up or macro photography. I used this to photograph some photos through a Nikon enlarging lens and a Pentax bellows. I believe this ring was made by Pentax due to the quality of finish. Please Text only to 250-880-3521
