Egami, the Japanese photography blog has uncovered a new Canon patent of a 10-120mm f/1.8 lens for an 1 inch sensor. Canon announced the XC10 camcorder in April 2015, with a 1 inch sensor and 4K video. The camera has not received many rave reviews and is just an opening shot for Canon in the non-professional 4K camcorder space. The EOS C300 Mk II camcorder equipped with Dual Pixel CMOS technology and 4K video is for serious filmmaking.
