Information about the Nikon mirrorless camera is so scattered, that when I receive anything from a reliable source, it is a big deal. The latest tip indicates that the sensor in the upcoming EVIL camera will have a 2.6x crop factor. Most of the previously filed patents also suggested a sensor with image diameter of 17 mm (diagonal) and a 2.5x crop factor - the difference between 2.5x and 2.6x is probably because of different rounding. If this turns out to be true, the Nikon mirrorless sensor will be smaller than the current m4/3rd format (diagonal: 21.6mm, 2x crop factor). On this diagram I added in yellow the approximate size of a 2.6x crop sensor:
According to the rumor, three new lenses will be introduced at the time of the mirrorless camera announcement: one wide pancake and two zooms. For reference, several mirrorless lens patents for different focal lengths were filed in the past. Note that Nikon may be obfuscating the designs and exact numbers in some of their patent applications.
