Jan, you are saying Repro ratio when you are talking about FOV. The
example is a clear one, but don't you have your example backwards? A
100mm lens on 35mm covers roughly the same FOV as a 50mm on a 4/3
sensor. It's the same as the way the 'standard' fl for 6x7 cm is about
twice that for 35mm. It seems to me that Skip is right, that will be a
problem for macro work in the field.

The thing that I'm concerned about is the working distance of the 50mm
E-4/3 macro. It produces the FOV of a 100mm lens on 35mm film, but it
could easily have the working distance of a 50mm macro lens, which is
pretty crappy for many applications.

Am I missing something? The 50mm on an E-4/3 should have the same reproduction
ratio for any given working distance as a 100mm lens covering a 35mm frame. In
other words, if a flower covers a 35mm frame at six inches with a 50mm lens,
that same flower will cover a 4/3 sensor at six inches with a 100mm lens, no?
