Reception The Nikon D300S has been tested by a number of independent reviewers, receiving generally favorable reviews. ''Digital Photography Review'' concluded in its extensive review: "The D300S is not the standout product that its predecessor was and unless you find your clients are clamoring for video footage, we can't see much need for existing owners to upgrade. But that shouldn't take away from an absolutely excellent product – a gently polished and refined update of a product that we considered a benchmark when it was released. "''ePHOTOzine.com'' said that there was "a lot of scoffing at the release of this camera simply due to its only visible upgrade which is the inclusion of video. But it doesn't look like Nikon have been sitting back on their laurels at all and I think this is a worthy camera to add to the stable."
