A Macro Setup for Field Use.
Here a 58mm f/1.8 lens is mounted on a Model I bellows. For magnification in excess of 1:1 the 49mm reverse adapter is used for better image quality. The Automatic Extension Ring is attached to the bayonet end (the front in this case) of the lens. A Double Cable Release synchronizes the lens and camera, closing down the lens aperture just before the shutter is triggered. The Model I Bellows is convenient for field use since the rail can be folded for storage.

The Maximum Topcon
It is amazing how many things can be attached to a single Topcon body. This setup demonstrates the flexibility and is really not one you would normally use. In addition to the body and the RE Auto Topcor 500 mm f/5.6 lens the following accessories are mounted:
    Bulk Film Magazine
    Motor Drive with Dry-battery non-cord Battery Pack and Hand Controller
    High Magnification Viewfinder with Right Angle Viewfinder and Model III
            Rubber Eye-cup.
    Accessory Shoe and Meter Indicator Light.

The Topcon Super D was, for many years, the official camera for the U.S. Navy. This sample shows the treatment they were subjected to. The film advance lever is broken and there is no flat surface, edge or corner without a major ding;  and the glass of the pentaprism had a large crack. Remarkably,  this camera still took good pictures--everything worked! A tribute to Topcon ruggedness.

A macro setup using the Model III Bellows mounted on the copy stand. The lens is the 30mm f.3,5 macro, attached to the 65mm cone adapter. The Macro-stage holds the subject. The pentaprism on the camera body has been replaced with the X6.5 High Magnification finder.

Below is an image obtained with this setup. The subject is halite crystals (common table salt).

These attachments converted the camera exposure system from measuring reflected light to incident light. When using these attachments, the camera is pointed towards the light source, rather than at the subject. They are valuable when the lighting conditions are unusual. Of course they have to be removed before the exposure is made.

The Meter Indicator Light
This handy device slips into the accessory shoe that is attached over the rewind knob. A small light  bulb back-lights the exposure needle to allow the photographer to adjust exposure even where there is insufficient local light. This might occur when photographing a brightly lit stage from the dark spectator area. Or, when taking photographs through a submarine periscope?
