Weel, he's convinced me. It is back to an all mechanical camera, learning the Sunny 16 rule so not electronics and film ISO of 25 so ther eis no chance of gamma or x-ray damage. Guess I was lucky to find that pre-Spotmatic Asahi slr a few months ago and have a coulple of others. Of course being all metal cameras, security will probably think it is hiding something and strip it down to the last screw.
