sentences:  The sensor captures image data at 14 bits per color channel through 12-channel parallel readout, which ensures 9 frame/s continuous shooting with higher bit depth than that on previous 12-bit sensors.Processed with the new Nikon EXPEED engine, the Live View mode in D3, along with D300, was Nikon's first implementation in its DSLR line-up.D3 also uses a stepper motor in aperture coupling mechanism for the first time, allowing real time depth of field control in Live View with exposure preview and live histogram functions.
