For me, the most maddening thing about using the M8 wasn't the noise issue, although I did find it annoying. It was the other problems that the camera had, i.e. the horrible AWB, the unreliability, etc. Some of the image "problems" that it has can be worked around if you take the time to massage the camera for the specific shooting environment one is in, and also take the time to massage the image further in post, but when you're using it as a photojournalist's camera – which I would – then the little idiosyncrasies that some people are keen to defend make it nigh unusable in the field, IMO.
The M8 has it's strong points. Some like it, some hate it, some are indifferent. But for me, even with my personal list of pros and cons, the big looming question in the room – the one that Leica needs to ponder – is: Is the M8 really worthy of the Leica name? My answer is "No." I'm sure some of you will agree and disagree.
To defend my point, I will simply ask you to compare the number of M8-bashing threads to the number of threads bashing the film-body M's. It isn't even a contest.
Any camera that has the name Leica on it should conform to a certain standard. That is what we, as Leica users, pay for: something that is as close to photographic perfection as can be achieved. Something that is reliable all the time and is of the highest precision. Something that I can turn to when I'm in trouble, knowing that I will still be able to get the shot. Something that won't decide to flake out on me when I need it most. Something that I don't have to second-guess in the field. As it turned out, the M8 was not that camera for me. I sent the M8 tester that I had back to the dealer and bought a used R-D1 instead, and I love it. It is reliable, consistent, and IMO it behaves much more like a camera should. I do wish it had an updated chip and a longer baseline, but for what it is, it's awesome and serves me well in the field. 'Nuff said.
I hope that when the M9 comes out I will be singing a different tune. But until then, I hope that those of you who are happy with your M8 bodies continue to enjoy them, and I hope that those of you who hate them continue to refuse to buy them; input from both camps will help Leica make an even better camera for the future.
