Canon is expected to announce a high end, full frame mirrorless camera, the EOS-90D and EOS-7D Mark III in the next 6 to 12 months.
A few Canon camera bodies have shown up as the company filed registration papers with certification authorities in various countries.
Canon DS126721 is registered with overseas certification bodies. This is most probably a new Rebel camera with built-in WiFi and Bluetooth.
Two DSLR test cameras are code named K436 (EOS-80D Mark II or EOS-90D?) and K437 (EOS-7D Mark III?). Additional mirrorless cameras are code named K424, K433 and EC 811. All the new cameras come with the DIGIC 8 processors.
K424 will be a 30MP full frame mirrorless camera and announcement is expected in late 2018 or early 2019. K333 will also be a full frame mirrorless camera but with less features and a lower price.
EC 811 may be the EOS-M5 Mark II APS-C mirrorless camera.
Sadly, I am not convinced the upcoming high end, Canon full frame mirrorless camera will fit my needs unless it comes with the EF mount. These are early days and there is little point in further speculation. Keep checking back for the latest information and development.
