Am I missing something in this "film vs. no film in camera" discussion? If
you're just using the camera to take a meter reading, it doesn't matter if
there's film loaded, the meter reading is "TTL" off the lower mirror not off
the film. If you press the shutter, the reading is then OTF, and you would
be taking a picture (and hence getting the correct exposure for the scene).
Having film in the camera only matters if you're pressing the shutter
release, and comparing the exposure times between the two cameras; then, of
course, the exposure time would vary and most likely be a couple of stops
off, since then the
"no film" situation creates reflectance problems.
But if you're just using the meter in camera "A", and you're exposing
film in another "OTF" camera, camera "B", then camera "B" should give the
more correct exposure since it will vary the exposure time from the metered
time as it is being taken. ( then you _would_ expect to see a difference in
duration. )
Right all?
