Nikon PB4 Bellows Description


This is the most versatile, (to date of production) of all of the Nikon Bellows Focusing Attachments. Depth of field can be increased and converging lines compensated for with the swing or shift of the front lens board. It has dual twin tracks. On the lower track, the camera and lens can be moved as a single unit for fine focusing adjustment without changing the lens-to-film distance. The camera can be attached to or detached from the bellows, or turned to a vertical or horizontal format at any position on the track. Duplication of 35mm film can be made readily with Model PS-4 or PS-5 Slide Copying Adapters. Reproduction rations with a 50mm F/2 lens ranges from 1/1.2 to 3.6X. Reverse the lens and reproduction ratios range from 1.6 to 4.4X.
