I found the mirror pre-release and (AC only) mirror lockup to be interesting features.
Phil has shown the camera as having color matrix metering and I don't see any evidence of this in Nikon's specs. If this is true, this would be the first mid-line body to have RGB metering. To my knowledge, only the F5 and D1 series have RGB metering.
Phil has acknowledged that the spec showing color matrix metering was a cut-and-paste error. The D100 doesn't have RGB matrix.
