The image processorExpeed 3A, a successor to the Expeed 3 used in the former Nikon 1 series cameras, features a new (according to Nikon) image-processing engine with increased speed of up to 850 megapixels per second. It is developed exclusively for Nikon 1 cameras.
The Nikon 1 V2 succeeds the Nikon 1 V1 and is succeeded by the Nikon 1 V3. The Nikon 1 V3 improves on the previous model with an 18.4MP sensor, built-in Wifi, FullHD video at 60 frames per second (non-interpolated), up to 120 frames per second video at 720p resolution, 20fps continuous AF, and 171 focus points, which Nikon claims gives better tracking autofocus than even DSLR cameras.
With the launch of the new camera, comes a number of improvements in features from the Nikon 1 V1. The improved sensor and processor have taken the pixels up to 14 megapixels, compared to the previous 10.1 megapixels with V1. Other improvements include a low light boost, faster action capture and improved lens selection.
