I´ve heard, that the "focal length", of the 2.0, is only 42mm at 1:2.
Olympus writes, that they recomend to use it reversed on the bellows and
that it will produce magnifications slightly larger than 1:1. Maybe it
is the same problem, as with the 3.5 (bellows to long for 1:1 with the
50mm Macro), but Mordmüller writes in his book, that the 2.0 is more
dependend on the floating element correction than the 3.5. This would
make the solution, to get 1:1, less optimal, to set the focus ring to
slightly lower rates as 1:2 with fully retracted bellows.
Do you know if the 80mm MACRO Zuiko will deliver better quality for
slide copying?
I guess the limiting factor for copy works is the film, at least the
film spec. papers (AGFA, Fuji, Kodak) suggest this. Some people recomend
to copy on a biger format to get all the detailes of the orginal, not
the way I want to go.
I´ve done so far only copy work to negative film.
