  • Olympus OM-1 Film Camera Review

    I found that 675 hearing aid zinc-air batteries are a a great replacement. And those are dirty cheap compared to the wein, which looks just like a 675 with an o-ring soldered in :). For cameras with bigger battery compartment (shaped to fit old mercury batteries) you could get an adapter (the one without a resistor) for cheap.


  • Awesome, I’ll try that, thank you!
