: I wouldn't be surprised if Olympus deliberately made the adapter a bit

this

This is probably correct.
Yesterday I did some photomicroscopic test shots using my E-300, the Oly
4/3 OM adapter, the OM-mount photomicro adapter L on my Olympus
trinocular microscope. I needed some serious refocusing when switching
the light beam from the normal observation oculars to the photo tube -
much more as when an OM body is mounted; this only needs some minor
finetuning.
The shots were ok, btw. I used the Aperture priority auto mode, a
positive exposure compensation (+1.5) and the new anti-shock mirror mode
(provided in the latest update of the firmware).
