[Leica] Fwd: more M8 Noctilux questions

[faneuil at gmail.com (Eric Korenman)]

UPDATE: With a deep breath and as slush fell from the sky (NE weather
right now), I took a 2mm hex wrench to my M8.

After about 20 minutes of fiddling and 50 or shots of distant street
signs and close ups of newspaper (!), my Noct appears to focus near
perfectly. My 35mm and 50mm crons seem to focus just fine as well.

It took the Noct to show me that the M8 was so slightly out of adjustment.

I know the M8 and Noctilux don't always get along focus-wise.
There have been many posts and it seems the common theme is a back
focus problem.

Here is my tale.

1) My M8 and lenses (50 & 35) focus perfectly.
2) Friend loans me his M6, assorted lenses - 35, 50 and a Noctilux.
3) On my M8, the Noct (shot wide open of course) back focuses by 4-5
inches in the near and mid fields. At infinity, the M8 + Noct will
focus slightly past infinity.

4) Now here is where I get confused:
The Noct focuses just fine on his M6. Infinity is dead on.
His other lenses focus perfectly on my M8 AND his M6.
My lenses seem to focus just fine on his M6 (IE, none focus past infinity)

Why does the Noct focus past infinity on my M8 and not the M6 if all
the other lenses work just fine on BOTH cameras?
