I think you're right, ROM preserves the R cam, so it just doesn't work on the SL and SL2. I don't have one to check, as I have avoided ROM lenses for that reason. Maybe I'll need to ROM if I go DMR. Another argument for EOS 20D or EOS 5D + adapter. >$1000USD converson costs on top of losing use with SL and SL2. Anyone know how well 3-cam lenses work with the DMR? Does it screw up the EXDIF? Is that only a problem with automated printing? BTW, John, what happened to BALUG?

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.
