John's optical arrangement is, as he says, based on mine from 2008... http://8mmforum.film-tech.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=8;t=000936# 000000 , the main difference being that my B&H 75mm (John uses a 50mm) lens is attached to the camera by filter rings. In my set-up shown I was doing frame by frame transfers, but as John rightly says, it can be as easily used in an "on the fly" machine. The reason such good transfers can be easily obtained is that the number of optical components is a minimum between film and sensor.... just two, the 16mm projector lens and the camcorder lens.... no mirror, no condenser lens, no ground glass screen. And of course the completely closed optical path ensures that no light leakage affects the quality of the images. The 75mm (50mm) projector lens is the equivalent of your (expensive?) Macro lens, both are simply what used to be known as "supplementary" or "close up" lenses. I used a 75mm to enable me to get the camera further from the gate and still be attached to the lens.... dictated by the projector construction. But it did mean I needed a longer zoom on the camera, which fortunately I had!
