Like the Nikon 1 V1, the 10.1Mp J1 has a CX-format sensor, which at 13.2×8.8mm is smaller than an APS-C-sized sensor and it results in a 2.7x focal length magnification factor. This enables the camera to be made much smaller than an SLR.
As the entry-level camera in the Nikon 1 series, the J1 has a three-inch 460k LCD and no viewfinder. Unlike the V1, however, it has a pop-up flash built-in.
