Finding a Replacement For Mercury Batteries

At this point I have several different cameras that require the old mercury batteries, which are no longer available. Since alkaline batteries have a different voltage and discharge pattern, some cameras cannot accept them as replacements because it would render the meter wildly inaccurate, and in some cases risk damaging the electronics.

The good news is that there are a couple of alternatives that work pretty well.

Converting Old Lenses For Use On Digital SLRs

I first discovered this unique and often overlooked aspect to the hobby some time in 2006. I had gone fully digital a couple of years prior with the release of the first generation Digital Rebel (300D), and I had some old Olympus OM and Canon FD glass that was sitting unused. At the time there weren't too many adapters out there (now the market is overflowing with them), but I did find an OM-mount to EOS-mount adapter, and that's how it all started.

Hopefully, if you're interested in getting started with adaptation of older lenses to a newer format, something in this post will be useful to you.
