This design weakness - light entering the viewfinder amazes me. I just don't
understand it. Alpa Reflexes made forty years ago had a photocell facing the
viewfinder connected across the metering circuit ( + to + and - to -) to
remove any contribution from light leaking in the back. A simple obvious
solution.
