This is a complete Nikon PFX manual camera system with a Graflex 4×5 large format back. The only item missing is a cable release. The camera consists of several assemblies. The main assembly is the shutter system housing. It contains a beam-splitter system on a swing-out hinge. For faster shutter speeds the larger chrome knob on the side of the housing is set so the prism will automatically swing back into place after the exposure is completed. When using time exposures the knob is shifted so the prism remains swung aside until it is returned manually after closing the shutter. The mechanical shutter has timed speeds from 1 second to 1/250th of a second plus B and T. The shutter speed is selected using the chrome lever and is indicated in the small window above the focusing telescope port. The shutter assembly also includes the focusing telescope with format reticle installed. On the base of the shutter is a phototube adapter for standard RMS size monocular photo tubes.
