I am one those hanging in there with the M8 still and love form factor, use of my M lenses, plus the RF shooting style.
This will be a great camera for me once the vertical band is fixed and we have good profiles in a RAW program.
In most situations the M8 performs very well.
My real remaining issue is that Leica needs to fix the new vertical band, whether it be hardware or firmware. It shows up in night street shots with car lights, neon, street lights. That type of scene is something that I happen to enjoy shooting a lot. My film M, D200, and even DLux3 have no issues with that type of shot while the M8 does.
I am continuing to take photos that I like with this camera vs. all test shots.
My dissappointment is that Leica would send the new "fixed" camera out into the world with this issue. All they would have had to do, is take a test shot of anything which caused the old banding and this new vertical line becomes obvious.
The vertical band is something that we should not gloss over, but is something that Leica must fix again. Let us hope that it was planned to be addressed in the 1.10 or higher firmware, although they should have stated so with the delivery of the 1.09 camera. If it requires another hardware change, then Leica completely missed the boat and did insufficient testing again prior to release.
I am hoping for the best and awaiting word from either Leica USA or Leica customer service in Germany.
