Nikon tonight confirmed the existence of the D3100, a major revamp of its entry-level DSLR. The camera in some ways is Nikon's best as it's the first mainstream model to shoot above 12 megapixels, at 14, and its first to shoot 1080p video. A new EXPEED 2 processor both improves image quality and switches on long requested video features, such as continuous autofocus and native recording in a more efficient H.264 instead of Motion JPEG.
