More than three years after launching the C300, Canon is refreshing its line of cinema cameras with the C300 Mark II. On the outside, the C300 Mark II is quite similar to its EOS siblings, although it does come with a slightly tweaked design that features a wider body. But the most important changes are elsewhere. For one, Canon has made the new cinema camera capable of recording 4K internally, via CFast 2.0 cards -- as opposed to the first version, which couldn't handle this type of footage natively. The C300 Mark II sports a pair of DIGIC DV 5 processors, an ISO range of up to 102,400 and a brand new 8.85-megapixel, Super 35mm CMOS sensor, which can shoot video at full HD (1,920 x 1,080), 2K DCI (2,048 X 1,080), 4K UHD (3,840 x 2,160) and, perhaps most importantly, 4K DCI (4,096 x 2,160).
