We're told Canon will let us know something at NAB 2016 in Las Vegas about the Cinema EOS C500 Mark II, though there may not be an official announcement.
We reported back in 2014 that Canon was gearing up to develop an “A” camera to compete with current market leader ARRI, and that the C500 replacement would like fill that spot.
We first reported back in April of 2015 that Canon was going to go above 4K in the Cinema EOS C500 replacement, and that such camera would be announced in mid 2016. Canon themselves confirmed this by letting the world know at Canon EXPO in September that they were working on an 8K Cinema EOS camera.
We expect to hear a lot more about the Cinema EOS lineup in the coming weeks.
