Well, I went ahead and bought one---untested from eBay, but the price was right---and I've just finished developing my smoke-test roll. Based on eyeballing the negatives, things look good.
What a fun little camera to use! It is quite a bit bulkier than the Ikonta 35, still pocketable but requiring a much larger pocket. The viewfinder is rather nice for the era, though I guess it would be considered squinty now. The little cyclopean rangefinder prism makes me giggle a bit every time I look at it, and the ergonomics of the body are really nice on the whole, especially considering the tight space into which they have to fit. The only thing I've had to get used to is the cocking lever, which is reversed from what I'm used to (push to the left to cock, rather than pull to the right) and kind of crammed up against the shutter release.
I got lucky and even the slow shutter speeds work, although I don't know how often I'll really use them; if I'm carrying a tripod, I might as well be carrying a bigger camera, but it's nice to know that in a pinch I can rest the camera on a rock for a longer exposure.
Suddenly I can see how people turn into photographic-history geeks. I can really see how this camera bridges some of the design space between the Ikonta 35 and the Contaxen, and it makes me want to run out and find a Tenax and a Super Nettel, not because I need them but to complete the evolutionary family. I suppose that would be a bad idea from a marital standpoint...?
