Digitaljournalist.org published what I think is the longest Leica M9 review I’ve seen so far. It includes size comparison with full frame DLSRs, SD cards test results, sample shots at different ISO (compared to Leica M8.2, Nikon D700 and Canon 5D), IR sensitivity comparison and more. The M9’s processor is listed as the only major flaw.
The conclusions (according ot the author David Keenan):
“Well, friends, the M9 is da bomb. Other than a fix for the “major flaw” described above, it is difficult to envision why an M10 is even going to be necessary.”
