I remember this '625eq' camera while browsing the links in Robert Monaghan's site long time ago. Recently I rediscovered the same while I again started browsing Robert's archived site.
A hand built, fixed lens, 35 mm wide-angle / wide-image panoramic camera made from a damaged Stereo Realist camera body and a 47 mm f8 view camera lens. If this were a medium format camera it would be 6 x 25 cm. The Realist's frame and film advance gearing were rebuilt to accommodate a new enlarged 24 x 102 mm image frame. Three scans are required to load each 102 mm negative into the computer. According to Ron Leven of Schneider Optical the 47 mm f8 super angulon lens has an image circle of 113 mm at f11, and a 40.5 mm filter thread. After many light drop-off tests I find this lens to be unusable without some kind of center filtering, and B&H Photo accepted a special order for a Heliopan center filter, but they never delivered. This project was my most interesting, but it is now terminated
This is so far the most detailed description I found about the panoramic conversion of a stereocamera:
Job 2--Lens Mount: I didn't want to do any unnecessary machining so I decided to use a screw thread focusing technique much like screwing a lid on a jar. In this case the jar is from a pressure transducer bought at an aircraft surplus store and a matching 55 mm threaded lid. The lens is mounted through the lid creating an assembly that is compact and easily removed. The jar was shortened and modified so the front cover could clamp it to the camera. The lens mount was something to be proud of until I discovered severe light leaks. Now it is light tight but kludged.
Job 3--Center Filter: The light drop off at the ends of my negatives is 2-3 stops, and none of my many hand made filters were usable. I have been using Picture Publisher software to correct the light drop off by using a especially created filter mask. This was satisfactory for a time, but is not a permanent solution. (See above photos for before/after comparison.)
Job 4--Focus Calibration: 1/8 turn = 20', 1/4 turn = 10', 1/2 turn = 7', 3/4 turn = 6', 1 turn = 5', 2 turns = 3', 4 turns = 2', 9 turns = 1' and 12 turns = lens fall off.
Note: The viewer lens is from a one shot Kodak pan camera, but it brackets the image and shows the horizon. When in doubt, I use the yellow bubble balance.
