Nice work, Peter, and good to see you back in the fold! As far as the focus
problem is concerned, I can offer a couple of pieces of advice based on my
experiences using OM glass on E-bodies:
Though I have not used a KatzEye, I did try an aftermarket focus screen in
an E-1. The screen has a split image focusing aid, just like an OM 1-3
screen (i.e. without the microsprisms). Manual focusing is much easier -
but metering becomes inaccurate with all lenses (even DZ), and by varying
amounts depending on the lens. Flash metering is pretty much impossible.
I have also used focus confirmation chips on E-410 and E-3 (the version I
had is not compatible with E-1), and they do work. They are sensitive (as
they should be) so it is very easy to focus through the in-focus point with
a manual lens (just as with MF cameras). The difference is that, unlike
with a split image where you can see the image coming into focus, with the
focus confirmation chip it's either in or out of focus, there is no "nearly
there" indication. A further handicap is that there is no indication of
which focus point is the one triggering the in-focus indicator. The E-410
itslef will indicate which of the three focus points is active, by way of a
red LED. The focus confirmation chip does not, which is hardly helpful
(though I suppose I could have manually selected only the central focus
point).
Knowing what I now know, I would use liveview. The E-3, on the other hand,
is much much easier to use with MF lenses, as the VF is noticably bigger and
brighter.
I have learned the hard way that there was a reason for Olympus to be so
reluctant to release the OM adaptor!

Today I experimented with an old 135/3.5 Olympus OM tele on the E-510. It's
like using a 270mm lens on a 35mm camera. Manual focus, manual stop-down,
aperture priority metering, and in-body image stabilization. I focused wide
open, then counted clicks down f/8 to shoot.

Focusing is difficult. If I keep using this lens, or my 100/2.8, I'm going
to want a focus confirmation chip on the lens adapter, and/or a Katz Eye
screen. Anyone with experience with either of these--how well do they work?
