It seems that the next Canon mirrorless camera to be released will be much more specialized: the EOS Ra, a full frame astrophotography camera. 

Nokishita broke the news, saying that the EOS Ra has been added to Canon’s product line and will likely be the next camera to be announced. This would not be the first such camera from Canon, with both the 20Da and 60Da having been designed for astrophotography, but it has been seven years since the release of the 60Da, and neither camera was full frame. A newer generation full frame sensor would certainly provide welcome improvements for astrophotographers, and paired with Canon’s excellent RF glass, it could make for a formidable combination.

Such a camera would be approximately four times more sensitive to hydrogen-alpha light (656 nm). This would make it difficult to shoot with for normal subjects, thereby rendering it a specialist tool, but for those who need it, it is likely a welcome addition to Canon’s product line. No date has been given for an announcement just yet. Nonetheless, with the EOS Ra, 1D X Mark III, and likely, a professional-level EOS R camera in the works, it is an exciting time for Canon shooters!
