It's not the manual wind per. se. that stops the fogging it's the method of
counting sprocket holes. If the P3t uses a geared sprocket wheel to position
the film for the next frame then it will not fog IR film. I don't know the
answer to this, my knowledge of Pentax cameras skips this generation. (I never
used those 'P' cameras I was happy with my MX). The ZX-M uses an IR sensor to
count sprocket holes for film positioning. A metal body and a solid film door
would help with IR leaking in from the environment but might not be essential.
