Both cameras have 12 million pixels, but the X10/X50 will feature a 2/3 sensor (smaller than M4/3) rather than the APS-C size used in the X100. It was also rumored that the camera would come with an optical viewfinder and be able to record 1080p video. Its 4x manual zoom lens has a maximum aperture of f/2. The price is $599 (approximately RMB 3,857), half the price of the X100.
