I see too much artifacting in these jpegs for serious use. Compared to my 5D mark 2 or Nikon d3S files they arn't very good. I believe the pixels are just too small to hold together. Files might work OK with a studio setup, but if you push at all on these files they are going to fall appart. Camera makers need to move in a different direction, different technology or stay around 12 or 14 mp with a APS or simillar size chip.
this is not the way to conduct new cameras and lens tests. You need serious photographers who understand lighting and will show us samples in professional settings. photosgraphers who treat these cameras as a serious work and not a happy snap. We also need to see processed intelligently raw photos. You can't tell anythng from these jpegs.
