I'm surprised no-one has mentioned the poor performance at even moderately high ISOs. At ISO 200, noise is noticeable. ISO 400 is apparently unusable for clean images.
I can't remember the size of this sensor, but if it's double the size of FF 35mm then you're going to use 1 stop smaller aperture for the same DoF as FF 35mm. That means half the shutter speed and in general a greater need for high ISO capability than 35mm DSLRs offer, not less 'high ISO' capability.
