A friend of mine gave me a beautiful OM-1 with some lenses. The only caveat is that I don't have any batteries for it. The camera takes mercury batteries. I was wondering if there are any options to replacing it or modifying it so I can take advantage of the built-in light meter.

There's some warnings here about using different types of non-mercury replacement batteries. In this flickr thread, there are a few suggestions:

  • use the PX625 replacement battery from Wein -- this is designed as a drop-in replacement for the OM-1, and even says so on the packaging. Downsize: expensive.
  • get 1.3V hearing-aid batteries from the drug store; apparently they fit and work.
  • Use readily-available 1.5V lithium cells, but either learn to read the meter as off or trick the camera by setting the ISO down by two stops. (That is, if you're using ISO 100 film, set it to 25; if you're using ISO 400, set it to 100.)
  • Get an adapter which converts 1.5V to 1.35V, like this one from CRIS. (Somewhere around $40.)
  • This place will overhaul your OM-1 to take modern batteries.
