Nikon had long since re-established its precedence in the digital SLR market, the news of the D3 and D300 took the struggle to a different level. If the D80, D40, and D40x were shots across the bow of their biggest rival, the D3 and D300 were broadsides, point-blank. The D300S is a 12.3 megapixel DX format digital single-lens reflex camera articulated by Nikon on thirtieth of July 2009. It alters the D300 as Nikon's DX format flagship DSLR adding HD video recording and that too with auto-focus. It has some similarities to the Nikon D700, along the same resolution, but has a smaller, higher-density sensor.
