The Nikon D2X digital SLR is a big investment for professional photographers. At around $4000, the D2X is not a blind buy, for sure. The cost is prohibitive for all but the pinnacle of Nikon-loving pros, and if you're one of those chosen few looking for an upgrade, the D2X might be the answer. It's a robust, high-speed camera with minimal lag time (37ms) and responsive tools that get all your settings and modifications ready to shoot quickly. The camera also supports an optional Wi-Fi link, and an optional GPS locator, which embeds your images with location information automatically.
