Didn't see the other thread. Been pretty busy, missing a lot of stuff lately.Thanks, Godfrey.
I was on a mad mission >10 years ago to collect a lot of information about many lenses. That cost a lot. Not at all easy. Plus, I have a room full of books on optics.
I asked about your Schneider (Robot) lens in another thread. If that (30mm f/5.6, a Tessar clone) has a variable focus setting possibility, it would make a splendid lens on the 6 (on a 7, it would have color shift issues). There are ready adapter possibilities.
Is that a "beamtenobjektiv"?
The compact Schneider 30mm lens is actually an f/4, designed for the East German secret police. The aperture is fixed, it has adjustable focus from infinity to "R" (reprographic, for document copying). The focusing mount has four marked positions. It's a very cool, very flat and tiny thing, very nice quality for the optimized range from close to middle distance.
Problem is that it's not a standard lens mount fitment. To fit it to the Star 50, you unbolt the standard Robot lens mounting flange and replace it with the lens using three longer screws. That makes it a little difficult to adapt to other cameras ... but of course, anything can be done with enough effort.
