Canon has unveiled a new version of its EOS-1D X digital camera aimed at the professional market, one it initially released four years ago. The EOS-1D X Mark II is an upgraded version of the original, housing a new 20.2-megapixel full frame CMOS sensor with dual DIGIC 6+ image processors, giving it a boost in terms of speed and image quality, as well as allowing it to film 4K and 1080p video at 60 and 120fps respectively with a "Dual Pixel" CMOS autofocus.
