I once owned an adapter that solved this for an OM-1, maybe there's an EOS
equivalent. It was a reverse lens adapter, to allow mounting lenses
backwards for flat-field work.
It also held the camera body's aperture coupling in the stop-down metering
position. So whatever light arrived inside the body was measured as-is, with
no adjustment for anticipated stop-down at the moment of exposure.
I realize EOS is electronically coupled, not mechanical, but maybe the
concept will ring a bell among EOS users.
