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.

I'd try the P3t if it was my choice. The problem in the thread
up to this point has been fogging by IR emitting sensors in the
camera body. I think these are associated w/ auto-winding bodies.
The P3t, if it is like the P30t I once had, is still a manual
wind body and I doubt that it would have these sensors. If the
little film window bothers you, tape it over w/ aluminum foil
covered w/ electrical tape. Do this before loading the film and
be sure to load & unload in complete darkness. Don't let anyone
develop the film unless they are familiar with and equipped for
handling it entirely in complete darkness. Lots of processors
also use IR sensors - don't let them take the film out of the
plastic film can in the light, either!  This is for the Kodak HIE

I agree with Bill.  I would use the manual wind body.  With SFX and Konica,
the film window should not be a concern.  These films are not as sensitive
to IR wavelengths as Kodak HIE.  I use a professional processor that uses
dip-and-dunk processing and have never had a fogging problem.  The data back
on the ZX-5 has not been the source for any fogging.  The main reason I use
the K1000 rather than my ZX-5 is that I prefer the all-manual controls and I
prefer to use a hand-held meter.
