Re: filmscanners: LS4000 slide removed from mount



Uhm, I think that's that word that Rob and I were trying to think of and
couldn't. :-) With a wide-angle lens, your image will tend to "spread out" a
little behind the shutter, rather than being cut off by it. I wouldn't have
thought it was a particularly measurable distance, but on 4-square it
aparently is, since Mr. Polloni has measured it. That's another disadvantage
of not being on the metric system in the US, IMHO. ;-)

Best regards--LRA

One thing that no one seems to take into consideration is the focal length
of the lens used. Take some photos on the same roll of film with your widest
wide angle and your longest telephoto. You'll find that the image size of
the wide angle is slightly larger than that taken with your telephoto. This
is a bit of a bugger when you're trying to file out the aperture of your neg
carriers.
