According to Newsshooter, Canon will bring a new codec to the Cinema EOS C200 camera in early 2018 as a free “upgrade”.
The new codec will be XF-AVC YCbCr 4:2:0 8bit and will be recorded to the SD slot, and not the CFast 2.0 slot.
Most of the world likely wanted to see a 10bit 4:2:2 codec in the EOS C200, but Canon does have a history of not wanting to add features to a product you can already get in a higher end product, and in this case, that is the Cinema EOS C300 Mark II. Canon also said that they have no intention of adding an internal 10bit 4:2:2 codec to the EOS C200.
