Canon's mirrorless lenses have gotten off to quite an impressive start, though the bodies still have some catching up to do when it comes to innovation. Canon might be pushing that envelope a bit next year, though, as new rumors have uncovered the potential release of the ROS Ra, a full frame mirrorless camera designed specifically for astrophotography.
Canon has previously released two such cameras, the 20Da and 60Da, but the last such camera announcement was seven years ago now. Furthermore, both previous cameras used APS-C sensors. Surely, astrophotographers would love the benefits of seven years of development along with a full frame sensor. Canon News recently uncovered what appears to be a page from the EOS Ra's instruction manual, which details that the camera is about four times as sensitive to hydrogen-alpha light (656 nm). Paired with some of the stunning new glass in the R line and with some of the likely forthcoming wide angle prime lenses, this could be a great potential option for astrophotographers, who frequently place high technical demands on their equipment and for whom specialized consumer cameras are relatively rare. Along with the forthcoming professional-level EOS R camera and 1D X Mark III, it looks like Canon shooters are in for some exciting times!
