Nikon D3s

The Nikon D3S is a 12.1 megapixel professional-grade full frame (35mm) digital single-lens reflex camera (DSLR) announced by the Nikon Corporation on 14 October 2009. The D3S is Nikon's fourth camera in Nikon's line to feature a full frame sensor, following the D3, D700 and D3X. It is also Nikon's first full frame camera to feature HD video recording. While it retains the same number of pixels as its predecessor, the imaging sensor has been completely redesigned. Nikon claims improved ultra-high image sensor sensitivity with up to ISO 102400, HD movie capability for extremely low-lit situations, image sensor cleaning, optimized workflow speed, improved autofocus and metering, enhanced built-in RAW processor, quiet shutter-release mode, up to 4200 frames per battery charge and other changes compared to the D3.
