Temperature was around 0 degrees F. This happened on my M6 ttl, which has an MP viewfinder (0.85), and my M7 with a .72 finder. Lenses in use were the 90 mm APO Summicron and 21 mm Elmarit (ASPH). The metering/focusing blocks and normal coincident focusing capabilities returned shortly after heading inside and letting the cameras thaw. The blocks vanished again within 15 minutes of going back outside in the afternoon (temp was about the same). And returned again not long after being brought back inside. Did keep the M7 under my coat some out of concern for battery performance, which was fine. I focused by judging distances -- the negatives look sharp -- but am curious about whether others have experienced this phenomena, whether they handled it differently (and how), or how to avoid it. Is this, perhaps, a signal to send the gear in for a check up (or maybe check my common sense and remain inside when the weather is so brisk)? Thanks. Greg Rubenstein
