Yes, If I had a M9 I could easily check.  As it is I made some infinity
exposures on film and am waiting to finish the roll.  I'll make some f/2
infinity shots.  It is interesting that the lens hits infinity fine on the
M2 as do the other lenses but not on the MP.  I recall that once or twice I
mounted a lens and the frame lines didn't come-up,  when I remounted the
lens it was fine.  I wish I could remember which lens it was, I think it
was an LTM and I blamed it on the adaptor.

Any progress on the 400' loader.  I discovered a Leitz bulkloader from 1939
that takes 400ft bulk roles.  It's called the Leitz Filmtank.  I missed an
auction in Germany by 2 weeks. It is a rare item.  It sold for like 200
bucks, not bad really.

Regards, Chris
