Just posted! Our detailed hands-on preview of the Nikon D300 digital SLR. Our preview covers the design of the camera, control layout, operation use, displays and menus. Also included is a closer look at the D300 implementation of live view including videos of it in use. We've also explored HDMI output and included a couple of 720p video clips to give you an idea of how high definition may change the way we use video output on digital cameras.
