Image Sensor: The Coolpix A900 features a 1/2.3" CMOS image sensor with 21.14-million total pixels and 20-million effective pixels.

Optics: The Coolpix A900 digital camera uses a Zoom-Nikkor glass lens for superb image quality. The Coolpix A900 uses a 4.3-151mm lens that is equivalent to a 24-840mm lens in the 35mm format.
