What is your favorite collapsible daily carry user between these 3?
I have an M2/M3 with rigid lenses. It's great when my intention is to go out to shoot, however I find it a bit too big/expensive/bulky for a daily carry. I would like something less expensive (incase it gets stolen/lost/damaged), more compact (so I can slip it into my bag), but still sturdy and with decent ergonomics.
i have this camera. I don't mind the viewfinder. It is bearable but still useable. The ergonomics are a bit awkward. I don't mind the film advance location but the shutter/aperture linkage is annoying. The size is great but it never seems ready to shoot. I have to fold it out and look at the lens and work with the EV system whenever I want to adjust the exposure. I don't think a better folder exists.
I do not have thsi camera. I think I can bear the viewfinder. The ergonomics don't seem as fast as the M but I have direct access for the aperture which is good enough. The lenses that I would consider would probably be the Elmar 50mm f3.5 or Summitar 50mm f2.0. I think the prices are comparable (between the two lenses) but the former is more compact and the later is faster. I figured that the both lenses wouldn't be the best to use wide-open though. The advantage of the Leica over the Retina is mostly ergonomics. Both viewfinders aren't the greatest but both are good enough for my purpose I think.
If I'm going to get a Leica IIIc/f + Elmar then I feel that I might as well get a Rollei 35. The viewfinder is probably the best of the two other cameras and I do not think the scale-focusing would be that limiting IF I were happy with an f/4-f/8 lens. (scale focusing f2.8 seems uselses but there are some other advantages of the Sonnar...speed is not one of them).
I don't want to own too many cameras so part of me wants the Retina for low light and Rollei 35 for good light. Or the Leica IIIc/f as a compromise. The cost is much more but the versatility is greater.
My selection is primarily between these three because I really prefer older glass and lenses. I don't like the automation of the Olympus cameras (XA, epic) but I keep epics because they are almost disposable (I got both of mine for under $10).
