Useful comment about the rear element - thanks.

The adapter in question contains some optics, so I'll ask about the
clearance of these as well.

I have one of the 15/4.5 Super-Heliar lenses that fit on a Leica screw
mount or a Leica M via an adapter.  I paid $450 w/finder, which was quite a
deal for a lens of this FOV.  As for light falloff, show me a lens of
similar focal length that DOESN'T have this issue.  The famed 16mm Zeiss
Hologon comes with a special center spot filter to correct its
falloff.  Stop the Heliar down to f/5.6 or f/8 and it's a real
winner.  Wide open, it doesn't fare so well.

Being a rangefinder lens, it has a deep rear element so the only way you'd
get it to fit on an OM body would be to use it on an OM-1 with the mirror
locked up.  But I don't know if the flange to film distance of an OM-body +
Adapter would allow the lens to focus.

A better alternative would be to buy a Bessa-L body for using the
lens.  Those bodies don't have any rangefinder, and can be had for about
$250 new (see B&H).  Look at http://www.cameraquest.com/voigtsys.htm for an
overview.
