Greetings,
I have just come into possession of a Mamiya 645 1000s with the PD Prism finder. The instruction manual states in no uncertain terms that a silver oxide battery, (such as PX28), must be used or "proper functioning of the camera cannot be guaranteed."
I am having difficulty finding a silver oxide battery, although 6 volt lithium batteries are everywhere.
So, the straight dope is..what? Non-silver oxide will work? Non-silver oxide will operate the shutter but cause inaccurate meter readings? Non-silver oxide will not only not work, but ruin the camera and cause plagues of locusts?
Help!
