[OM] False metering On OM-1

[Stylianos Georgakis]

Hello Zuicoholics,
Lately it is difficult to get Mallory PX625 batteries for my OM-1. So I had to 
use PX625A alkaline instead. Since then the meter gives me 1-2 stops 
overexposure readings when compared with my handheld Gossen Luna Pro SBC or my 
other bodies. Any suggestions?

Best regards,
