Last week we reported on a Canon patent outlining development of Quad Pixel autofocus. The tech involved is fairly complex, but in a nutshell, Canon is trying to improve on its current Dual Pixel AF system with an improved version that addresses the current limitations of the decade-old DPAF. However, filing technical data in a patent is one thing; putting such tech into real-world use in a production camera is quite another, potentially taking years, and that's if it ever materializes at all.
Fresh rumors hint at radical new AF system coming to Canon EOS R1
