I am using an early version of the Russian "Dandelion" which is pre-coded
with the lens FL. Later versions allow the user to program (and re-program)
the FL into the chip. To say the programming procedure is "arcane" would be
a misrepresntation. Suffice to say that I am happy with the pre-programmed
version!

KatzEye claims little impact on metering with the E-510 screen
<http://www.katzeyeoptics.com/item--Olympus-E-510-Focusing-Screen--prod_E510
.html>
but only for ZD lenses. They warn that: "Meter performance may vary
significantly when using non-ZD lenses with a mount adapter." However, they
also state: "Please note that all metering testing was done using Zuiko
Digital (ZD) lenses." It's difficult to square these two statements if
they've never tested non-ZD lenses. I think I'd call them to see what they
really do and don't know.
ps: Which focus confirmation adapter worked? I never use anything but the
center focus point and can't imagine allowing the camera to choose the focus
point.
