Here is how to manually adjust the new Nikon D3s in movie mode. this is coming out of Nikon Rumors but it looks to be solid.
The Nikon D3s User Manual does not explain how to manually control the camera while shooting movies.
Nikon clearly missed advertising this very important feature of their new camera.
With the new Canon 1D Mark IV hitting shelves in a few weeks, this could be a costly mistake for Nikon.
