The Nikon D300S features 24p video at 1280x720, with an external microphone input. DX (crop) sensor.
It also features limited autofocus in video mode. The D300S will auto-focus on a fixed point in the frame.
This page hints that it might have some manual exposure control (thanks @tylerginter!).
Nikon also clearly learned from Canon in that they got the camera into some pro shooters’ hands before its release:
Rolling shutter is either greatly improved from the D90 or it’s being expertly hidden in editing.
You can pre-order the D300S now from Amazon. $1,800, body-only.
