The D70s builds on the success of its popular predecessor, the D70, with multiple internal and external refinements including an improved autofocus system, larger LCD monitor, the addition of a remote cord port, new graphic user interface, among several other enhancements. Designed for a broad range of consumers from experienced and amateur photographers to beginning photo enthusiasts and hobbyists, the D70s offers a proven track record of superior image quality, robust performance, and advanced new features. Its DX format 6.1-effective megapixel CCD sensor is optimized to deliver images with excellent sharpness and clarity. An improved autofocus system delivers enhanced performance, especially in Dynamic area AF and Dynamic area AF with closest subject priority modes. This combined with Nikon's unique Dynamic Buffer technology (that allows the camera to continuously take up to 144 pictures at a speed of three pictures per second*) makes the D70s even more responsive when photographing fast moving subjects.
