Geoff:

I'm sure it will eventually be fixed in firmware.  Both the radial and 
asymmetrical shifts were issues that Kodak had on its own cameras.  My point 
was that the M9, like the M8, was released to "it's perfect" cheerleading by 
hardcore Leica enthusiasts - and that again, waiting for the 2010 production 
run (or firmware, more likely) is starting to look like a good idea (for the 
same reason you wouldn't buy a car the first year a new platform comes out). 
 Of course, with Leica's "let's spend as little as possible" development 
budget for M cameras (and now digital Ms), it could take a while.

Leica will fix this color shift problem because it has to.  One of the three 
major selling points of the M9 is that "wides are truly wide" (the other two 
are resolution and the ability to use your old lenses)  But when you get to 
21mm and below,* if the "wides that are truly wide" are limited to are 
newest-generation lenses in the $5,000-6000 range, this is not a very 
compelling point.  And buying a new lens defeats the "re-using old lenses" 
justification: once you are buying a new camera and new lenses, you might as 
well be cross-shopping other systems.

And let's not all be intentionally blind about the fact that Leica sells 
(and historically has sold) bodies *because* people have collections of 
other manufacturers' lenses (or because those were available).  That's the 
only reason why manual lens coding made an appearance on the M9 - because 
all Leica lenses that could be used with the cameras could be coded.  So 
that leaves?  Cosina, Konica, Zeiss... Leica has, historically, had a 
symbiotic relationship with other optical manufacturers, whether authorized 
or not.  C.f. the 1950s, when the only way Leica could sell cameras in the 
United States was to combine them with Japanese lenses that were subject to 
a lower duty.  There may have even been no post-war IIIc, IIIf, IIIg, or M3 
without that.   Then there was the Minolta CL/CLE arrangement.  Then the 
modern question: why did Leica allow Erwin Puts to publish, on Leica's web 
site, a Leica lens book that included the 15mm Cosina lens?

Best,
Dante

*I know from experience that a 15mm CV works fine on an M8 as a "21mm" lens, 
and I haven't seen any systematic complaining about the 12mm as a "16mm" 
lens on that platform.  Any focal length longer than that is either 
correctible by taking a step backward or getting one focal length shorter 
(for a couple of grand, max...).
