The M's are the gates of the 9th Circle of Hell for sure. I have the M8.2, M9 and M240 and all are good for their individual reasons. And i have seen them all damned in print. That's fine. I get good pics with all of them, that is to say the IQ and color are good. An additional problem with these old Leicas, other than failure and batteries, is that one is lured down the path of retro lenses. They seem to go so well on the old M bodies. I have old and new lenses and a new "old" lens. The colors are nice. And I have the HB X2D with the XCD 55V which is a great combo, HB color science is wonderful, 16 bit dynamic range, even the HB 8 bit JPG is great. And the color is quite comfortable but it does not seem to have the romance of something out of that M9 with a good lens like the SBS 5cm. Even the newer lenses like CV's look good on the M9.
And that is my dilemma as I do not like how Wetzlar's Trolls support older bodies. I am also fond of the bodies. I've stocked up on the M8/M9 batteries and have two for the M240 but worry that one or all of the bodies will fail and Jadon at Red Dot will not be able to use his mojo to fix them. I have other cameras but we all have the same problem, "Do I have enough cameras?"
To be truthful if I thought the camera would make me a better picture taker I'd buy a bunch. And as The Good Book admonishes us, we cannot buy our way into Heaven, neither can we buy our way into skill. Drat. ;o)
