The Nikon D4 is the company's newest flagship full-frame professional DSLR, offering a 16.2-megapixel image sensor and 10fps continuous shooting. The large sensor and relatively low pixel count maximizes the camera's low light potential, offering a combination of speed and flexibility designed to appeal to news, sports, and action photographers. The D4 also comes with a host of state-of-the-art features to appeal to both photographers and videographers, including support for the new XQD memory card format and a maximum ISO sensitivity of 204,800. Overall, the Nikon D4 is a durable, professional workhorse for more than just weekend warriors. It will begin shipping in February for an MSRP of $6000 body-only.
