Not directly connected to the original subject, but I tested the HDR feature on the D800 for portraits today. The setup was two Kino Flo 400 Diva-lites giving 1/300 at f:11 with 640 ISO with 85mm Nikkor T/S, camera was on tripod. Only one shot out of 10 was totally sharp, in all other shots the model had moved just slightly during that 2/10 of a second or so. In this context slightly means more than 1/3 of a thickness of an eyelash. Head needs to be clamped if shooting HDR (for pixel peepers at least)...
