Tom,
I might be misinterpreting your excellent explanation, the only thing
which makes me wonder is ROM effect on pre-R8 cameras. ROM lenses meter
just fine at all metering modes for R-series bodies (R3-R9) because the
third cam is still installed on the lens. ROM lenses just don't work
with Leicaflex bodies because of the absence of the first and second
cams.
Cheers,
John Gong
