Nikon PB-6 format_4x5 The SMC Pentax-M 50mm f1The Nikon PB 6 is a sturdy late model bellows that features autodiaphragm capability (with the AR 7 double release, not included) and a built in stage focusing system. Accepts any Nikon F mount lens; the camera end is a standard F mount but practical compatibility will depend on the shape of your camera (some bulkier AF and digital cameras will require an additional extension tube not included to clear the back of the rail). In near new condition.
