I would love to have fast access (like for ISO and EV) to switch on bracketing.
Or maybe an option in the menue to program the "self timer" position of the switch as "bracketing on" position.
I now use it very often for landscape stuff-but when I photograph people in between I want to quickly switch it off and afterwards back on.
Typical problem on a sunday afternoon walk in harsh light.
The vignetting correction of jpgs seems less intensive that that of the DNG converted in c1. I think the jpg-vignetting correction for some lenses could be a little stronger.
Last: I feel the M9 is very slightly less responsive than the M8-I think I read something that the shutter delay is very slightly longer and I believe that I feel it. Dont know if this can be speeded up.
Overall these are all minor points and the M9 is a great camera IMO.
