I mentioned that possibility a couple of years ago. But who has
really got the time to spend on it when that time could be spent
making photographs. My solution is to stockpile a few extra
bodies and hope they don't stop making 357 batteries and film.
The metering circuits of the OM-4t is the real trick. I'm sure with
todays electronics, much could be improved, calibration without
pots, rear curtain sync, .... but in the end you really don't end up
with that much more. Life moves on, we get older...
When I got technical, a teacher told me to just go take some pictures.
And thanks to John and Clint, who probably aren't getting any younger
either, who help keep it all going.

The material cost is not the issue when you figure in time and effort.
