Re: Nikkor coverage

[Robert Erickson <cirkut8@xxxxxxxxx>]

Take it as a fact that a 24mm Nikkor lens coverage
will vary from year to year.

I have experence building LarScan rotational cameras
with many different brands and models of 35mm format
lenses. I have learned the hard way that the coverage
on 120/220 film using the same focal length lens will
vary a lot, even using the same focal length lens from
the same manufacturer!

The beauty of using stock lenses is that you can build
the camera with any stock lens and then later find the
model with the greatest coverage.
