Nikon PS-5 Slide Copying Adapter enables reproduction of 35mm transparencies in black and white or color, either full size or cropped and magnified. This unit is designed for the Model PB-5 Bellows. This unit has almost the same features as the PS-4 with the exception for film strip trays and the frame-shifting mechanism. It is used with the PB-4 or PB-5 Bellows. It also has trays for rolls of unmounted film and a magnet to hold the light-tight bellows shut when not in use.
