The D70 employs the popular Nikon DX Format sensor and Nikon F lens mount design. This maintains seamless compatibility with all AF Nikkor lenses while allowing photographers to take full advantage of high quality DX Nikkor lenses designed exclusively for Nikon's D-series digital SLR cameras and optimized to achieve outstanding center-to-edge-to-corner image quality. The D70 is ready to use the instant it is turned on. The 5-area autofocus system is fast and precise, and includes an AF-assist illuminator to help maximize performance even in dark shooting conditions. Controls are located for easy access and smooth operation. Menus are presented clearly and in plain language on the large LCD monitor. All the camera's systems have been optimized to deliver quick response. And, innovative shooting options have been added to simplify the photographic process, whether controlled manually or via advanced automatic operation. Shutter speeds of 30 to 1/8,000 sec. ensure full creative control. The built-in auto pop-up flash can synchronize at shutter speeds of up to 1/500 sec. for great fill flash effects. Sensitivity can be set between ISO 200 to 1600 or controlled automatically across the same range of settings to maximize available light. A 6.1 effective megapixel Nikon DX Format CCD image sensor featuring wider dynamic range and a higher signal to noise ratio produces 3,008 x 2,000-pixel images with high resolution and superbly sharp details suited for making large prints, or for cropping for creative detail. The D70's advanced System LSI processor is programmed for next generation performance to produce the finest in vivid colors and clarity, while maximizing the speed of file compression, memory buffer handling, simultaneous recording of JPEG and NEF (Nikon Electronic Format) files, and near-instant LCD image display.
