[LRFlex] Trouble in LeiCanon Land

Y'all -

Did some less-than-casual lens tests today in order to make some decisions about what to bring on an out-of-town trip. Shot a few lenses (mostly Leica) at 2.8 & 5.6. Aperture priority, "pattern" metering, self timer, tripod, ISO 100, Fotodiox adapter..

Houston, we have a problem...

All the 2.8 shots show significantly less exposure than the 5.6 shots. Longer lenses show more difference. Brand of lens makes no difference.

Geeezz...

Anybody got any ideas? Mirror beam-splitting effect??
