Nikon 1 V2 review
While the two first-generation Nikon 1 system cameras used the same 10-million-pixel, CX-sized (1in/13.2x8.8mm), CMOS sensor, the J2 and V2 have different resolutions. The J2 keeps the original sensor of the J1, but the V2 has a new 14.2-million-pixel resolution.
The increase in resolution isn't huge, and neither should it be with the sensor being smaller than its competitors. Any dramatic increase in resolution would potentially affect image quality by reducing dynamic range and increasing noise. To give an example of what the difference in resolution means for photographers, at a print resolution of 300ppi the new V2 is capable of producing images that measure 15.3x10.2in, which is a moderate increase of 2.4x1.6in compared to the original 10-million-pixel sensor. The 4608 x 3072-pixel-resolution images can be saved as JPEG or 12-bit raw images, with an ISO sensitivity of ISO 160-6400.
One of the most impressive features of the first-generation Nikon 1 system cameras was the powerful processor they possessed. This has been improved further in the V2, which now uses the Nikon Expeed 3A processing engine. It is this powerful system that allows the V2 to shoot at a frame rate of 15fps while the camera is autofocusing. This is very impressive and almost unrivalled for a compact system camera.
