One more of the Bessa... after just a couple days short of a month of waiting for arrival from Ural region of Russia, the R3m has a black Jupiter-8 ... worth the wait based on initial impressions. Steve you were right a couple weeks back - very nice match indeed. I'd love to throw the Helios-103 on here as you've done, but can't justify the adapter... as months wear on perhaps I'll find a way to do so.
EDIT: Hmmmm... I may have spoke far too soon. Just found quite a bit of dust and/or cleaning material bits inside the elements. :-/ Didn't notice til they caught a particular light. Also there appears not to be a single shim between the optical and focusing portions. Anyone know if these later black version did not have shims? Now I'm worried about RF accuracy with this thing, though I don't have a ground glass to check with.
EDIT-2: well, it does all appear to be just fibers and not scratches, so probably won't matter much. Overall I'd say I overreacted.
Still am concerned about the lack of any shims however. We'll see how this roll turns out.
