Canon Japan has released a teaser for an 8K Cinema EOS camera, one of two 8K Cinema EOS cameras I expect will be announced in 2021. We'll likely get an “A-camera” 8K camera above the Cinema EOS C700 FF and an 8K camera with a modular design like the Cinema EOS C300 Mark III and Cinema EOS C500 Mark II.
It turns out a marketing presentation was made at Inter BEE 2020 ONLINE a few days showcasing what Canon has planned for 8K.
As a leading company in imaging technology, Canon is working to develop 8K solutions in anticipation of further advances in image expression. A compact, lightweight 8K camera that can be used in a variety of shooting styles. EF Cinema Lenses boasts an extensive lineup of wide-angle and telephoto lenses. 8K display with high brightness, high contrast, and high color gamut. The blending of four real 4K projectors enables a large screen projection of real 8K images. From input to output, the Canon 8K solution provides an unparalleled viewing experience
Canon did show off a modular 8K Cinema EOS camera, as well as an 8K conversion box. For the moment it's not fully understood what the conversion box is for. The best guess from YMCinema is that the box is for 8K output, as the camera will record 8K internally.
I suspect we'll hear something from Canon USA in the next little while.
