The fact that Leica customers used to use non Leica lenses on their film bodies does not mean -all- of them will work with with their digital bodies for the reasons that have been quoted very many times over the years. When Puts did his lens tests on the 15mm CV lens Leica were not only still only making film cameras but had made it clear that most RF lenses were not suitable for digital. After much pressure from the market Leica have made a brave, and IMO successful, attempt to resolve these issues. It leaves a tiny number of lenses both Leica and other makes, most designed when digital was unheard of, that are not compatible. They cannot repeal the laws of physics. Compensation for colour errors and vignetting can be made up to an extent, though it has other implications on dynamic range. Most of my life the widest lens used on an M was 21mm, now we have the 16mm WATE. I don't know what the winging is about. The vast majority of M mount lenses work brilliantly, a tiny number are incompatible. There is no colour shift on the compatible lenses, so stick to using them. If there is a non-Leica lens which needs correction software to work on the Leica then its manufacturer should supply this to its customers. It has bugger all to do with Leica.

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...).
