I suspect the most practical way to start would be to compare the DOF
tables for one of the E-1 lenses against the 35mm based DOF table for
the 24mm (which you can find on the eSIF). Unfortunately, the
instruction manual for the 14-54 lens on Oly's web site doesn't include
an DOF tables.
Anybody know wher one can find DOF tables for E-1 lenses? Even if the
focal lengths aren't exact matches, one could at least discover the CoLC
they are using.
