I'm curious how the M8 + ASPH lenses compare against the Epson + CV lenses. May not be worth the M8 price if the difference is simply not large enough.
All the image quality difference is moot at this point because the M8 is riddled with a host of problems:
(in increasing order of severity)
1) Back focus issues - this is not a big problem really, but with Leica, you stand to wait up to months to ship your camera to Germany, get it fixed and get it sent back. I attended this recent Leica seminar where one of the attendees was lamenting his M8 was still in Solms and his R9/DMR was there for 3 months before to fix a loose switch
1) Leica offers 2 free IR cut filters with every purchase, which may or may not be enough for your lens collection
2) Filters can take weeks, if not months to arrive
3) Third party IR cut filters are available, but "are not guaranteed optimum results" with Leica's latest firmware
4) Filters were originally supposed to be from B+W, but somewhere along the line Leica switched to a Japanese company. Some say Hoya. Whatever.
5) You DO NEED those IR cut filters to get accurate colour without the nasty magenta cast due to the overly sensitive nature of the sensor to IR sensitivity
6) You can of course PAY for those Leica IR cut filters on B&H, adding additional expenses
7) Firmware 1.10x is now out which fixes the cyan corner cast issues with lenses 35mm and below, but you need to use it in conjunction with properly coded Leica lenses with the appropriate IR cut filter. Yes, if you want to have accurate colour with the M8, be prepared to switch to Leica lenses only (AND pay $200 for each to get the 6-bit coding) or be prepared to hand code your VC / Zeiss and other third party lenses. Even then, the firmware may or may not help you with the cyan drift problem, depending on your IR cut filter (Leica's or B+W's or other third party ones) and lens' focal length. It's now a closed system buddy!
8) Firmware 1.10x does not fix EVERY cyan cast problem. It still depends on the white balance at the time of the picture and a host of other myraid factors etc etc.
6) Nasty green banding when point light sources are placed at the edge of the picture area. Not resolved as of yet, may pop up anytime.
7) And the last issue, which is the most serious, is the as yet unresolved Sudden Death Syndrome (also known as the SDS). Buying a M8 today is a little like Russian Roulette - you never quite know what you are going to get - a perfectly working body, or one that will die on you suddenly in a few days, weeks or months. Even some who had previously gloated over their working cameras experienced this. The only "fix" is to send this to Germany - some have done so and have their cameras returned without any work cos it was working by the time it got there and Leica couldn't find anything wrong with it. Some have had it happen a few times even after they got it back.
So, buyers beware!
