Canon filed a patent for a 10-120mm f/1.8 lens for an 1″ sensor. This patent makes you think about the XC10, Canon recently announced professional camcorder with an 1″ sensor. Might this patent refer to a replacement, or to another model? I can’t say for the time being. The XC10 has a 27.3-273mm focal range equivalent, and the fastest aperture is f/2.8.
