Everyone: thanks for your comments and likes. I've been absent again and have gone through the last couple pages and added my likes. Please excuse my brevity of comments at the moment.
Peter: thanks for your additional feedback. That's pretty much my feeling of how the M9 will work in the cold based on my experience with it last year. This year it's definitely different and it can't just be firmware related, as I believe I've been using the same firmware for over a year. I have five batteries and can use them all in one day, such as at weddings. It's an aspect of the M240 that should be an improvement, as noted by Adam. Three batteries should last forever. I was out a couple more times since last posting. Once over the weekend during a snowfall where temperature was just below freezing, and the camera worked fine. Yesterday I was out during a blizzard during which the temperature was lower by a few degrees, but it was very windy. And the camera started locking up again from pretty early on. I was using my 'best' newest battery too... Basically, if I shot more than one image while the camera was writing to the card, there was a high probability of losing all but the first image. So, for the rest of the outing, I would only shoot one image, then wait until the red activity light turned off before making another image... I still haven't tried the latest firmware, or my hand warmer theory. To me at least, something doesn't seem right with the camera if this is happening now, but wasn't a problem last winter in similar conditions, same firmware, etc..
Adam: thanks for your thoughts and agree the reasons you mention as advantages for the M240 are also attractive to my style of shooting. Regarding CCD vs. CMOS rendering: I agree here too! When the M240 started shipping and people were posting side by side M9 and M240 DNGs, after playing with a few sets, I found it to be relatively easy to equalize each to the other. Yes, they each require different settings, but it is possible. I've been a Canon shooter for ages, and having recently tried a number of Sony cameras, I find both have similar qualities to their files as starting points, and therefore am used to the supposed flatter 'CMOS look' which likely will also be the case for the M240. I believe this might actually be a good thing for the wedding work I have coming this year, which will all be processed by someone else used to processing Canon files.
Interesting observations and theory about sensor reflectance affecting lens rendering. I can believe this could happen, as it's been known a long time that light reflecting off the sensor and back into the lens is a cause for image degradation. I would think Leica's lens designers would compensate for this in their latest designs, but one wonders about somewhat older lenses such as the 28 Cron...
