Hi, I just purchased a beautiful MT167. I own already an AX and another MT167. I own as well two 50mm f1.4, one 135mm f2.8 and one 28mm f2.8, all from Zeiss. The issue I have with the latest MT167 is that f number is shown different on the screen than it should be, difference is more or less 1/2 diaph. For example the ring is set to f16 and the screen shows f19; at the opposite side it shows f1.7 when the ring is set to f1.4. This happens on 3 of 4 lenses. None of the other bodies has this problem. I think about a small body gap somewhere. Anyway, does it change something on the shot condition, or is it just cosmetic on the screen?
