Otherwise the Nikon D800 is a highly dependable and capable camera that offers a versatile and improved auto focus system, an enhanced viewfinder with 100% frame coverage and a very good movie mode.

For example, in our shots taken a gym that was dimly lit by sodium lamps, chroma noise is clearly visible from around ISO 2500 when the images are viewed at 100% on the computer screen.
