I have an R3A, and although I am quite happy in general, I have reported several issues:
- I find that I am clumsy enough to have frequent problems with correct winding lever action, and this creates uneven spaces between the frames on film - this doesn't happen on my ZI
- the black paint on the rewind knob has started to go away after just 3 or 4 months of moderate use
- unless I put on a lens as heavy as the 90 Elmarit, the camera tilts heavily backwards, and I find it annoying
- the RF is misalligned at infinity and I will have to fix it - this has happened to my ZI too, so it is not an issue related to any particular brand I think, but Bessa is not immune to this
- the winding lever has become quite tight, and at times it does not snap back after the winding action by itself
The focussing is ok, and with longer lenses it gets better with the 1.35x viewpiece magnifier, while the shutter and autoexposure work well, even if the shutter is not very quies - it gets toned down a bit if you use a half case...
So, here you are, I will dedicate the R3A to the 75mm and 90mm lenses and be done with it, but in all honesty, if I had to decide the purchase again, I would have saved up for a second ZI, this camera is such a joy to use... (and it costs twice as much... :-( )
My R4A instead, is working better and would be impossible to substitute with the ZI, so if you are a wide angle guy, you could start with this one.
