Well my M8 arrives tomorrow according to UPS. So, I will see for myelf. It does certainly appear that there are some issues with image anomolies. I hope that either, it's limited to a few cameras or Leica comes out quickly with a fix. I will not shoot around it, if it's exhibited in my camera and no fix is forthcoming, It will go back. OTOH, I am not unimpressed by many of the shots I've seen so far, as some have said they were. I think they look as expected, (banding shots excepted of course). There have not been many really good photographs, but certainly some.
I am not blindly loyal to any company. I expect Leica to handle this correctly, as did other companies when it happened to them. I have no reason to think they won't so I am remaining calm about it for now.
Perhaps, I'll kill this thread, which has had more views than any other up currently. But, I will reiterate my belief that many people have held out expectations for this camera that were just not justifiable. Enough said.
