Apologies if this subject has been raised before, but I've heard that M6 rangefinders have a tendency to "flare" in certain light conditions making them difficult to focus. I came across this criticism again when reading a Net review of the Bessa R2; the reviewer stating he preferred the Bessa to the M6 as the rangefinder was brighter and not prone to the flare exhibited by the M6 in bright light.

Have M6 users encountered this? Would it deter you from purchasing another one?
