Three years after the D4 was born, Nikon's now introducing the highly anticipated successor to its flagship DSLR: the D5. Nikon says the camera is built for speed and accuracy, featuring an insane 153-point AF system, to help cover an extremely wide focus area. Inside, there's a full-frame 20.8-megapixel sensor, a 12 fps continuous shooting mode and a freshly designed EXPEED 5 image processor -- which the company claims is capable of creating "true to life masterpieces."
