, which is rated 1.3 stops lower by DxOMark on their low-light ISO score (1320 ISO vs. 3253 ISO for the D3s).

Low noise videos are valuated useful. While not officially documented in user's manual, D3s indeed features the full manual control in D-Movie mode, including aperture, shutter speed and ISO. This feature was reported and posted by various users and eventually confirmed officially.

On December 21 2009, Nikon announced that NASA had purchased 11 D3s bodies and assorted lenses for use in the US space program, including on the International Space Station. The D3s cameras are identical to the model sold to terrestrial users and will be used unmodified.

In April 2010, the D3S received a Technical Image Press Association (TIPA) 2010 Award in the category of "Best Digital SLR Professional". In August 2010, the European Imaging and Sound Association
