I am also positive that the negatives might come just ok but I am just bugged by it. It doesnt seem like it is batteries then?
Maybe as Pan says it is just wrong info on the viewfinder but the real shutter was correctly chosen during exposure?
P.s. My test scene wasnt uniformly lit but both OMs gave the same overexposing shutter reading.
The LR44 battery looks to be at low voltage, I would replace it with a fresh battery of good quality just to see if it will ameliorate the problem.
Remember, that many batteries advertised as silver oxide are nothing more that alkaline batteries and don't have the long term current capacity when a load is applied, although they might read at the right voltage when tested with a VOM.
