Re: Duplicating 1950s era stereo slides?? Personaly, I would go a completly different route. Back when 35mm slides where popular, you could buy a 35mm slide duplicator. It had a place to stick in the slide, some horizontal and verticle adjustment, and often a T-Mount to use on most cameras. You pointed an external flash at the duplicator and snapped away. The better ones had adjustable focus and there were really high end zoom ones that allowed you to magnify a portion of the image, The esoteric features such as through the lens flash metering are not needed, once you get the exposure calibrated for your film and slides, you can just keep snapping away. You may have to experiment a bit to get the best results, trying different films and exposure. If you want to just make more stereo pairs then you use 1:1 magnification. If you want prints or scans, then "zoom" it up to full frame (not quite, many stereo pairs are slightly wider than half frame) and use negative film. Then you can just take the film to your favorite lab and get prints (which can be viewed with a hand viewer) and scans at any resolution you want. A cheap setup is probably a junk box item and can be had for very little money. A really good one that goes on a real flat field macro lens (not a zoom with a "macro" setting), would go for more. Nikon sold one at one time, and AFIK, so did Canon, Minolta and Pentax. A quick web search yeilded such things as how to build your own for almost nothing, One for a camera with a fixed lens: http://www.bugeyedigital.com/product_main/bow-sdd.html The same unit was sold under several brand names for varying prices. Here's the kind that go right into the camera. This listing is for Adorama who no longer has any in stock. http://www.adorama.com/CESDZ.html B&H also did not have a similar model.
