I wasn't specifically looking for a shift-'n-tilt bellows with auto
facilities. I just wondered whether they existed (without auto, which
will be hard to manufacture). I am sure you can stop the lens down
when mounted on such bellows.
And with the reversing ring: I always put a NON-auto 7mm extension
tube at the free rear end of the reversed lens. After that it can be
stopped down manually by rotating the aperture ring. Any other
NON-auto adapter which fits to the rear of an OM-mount lens does the
job equally well (e.g. T-adapter)
