Since the announcement of Canon’s Dual Pixel Autofocus system, introduced with the Canon EOS 70D, we kind of knew that Quad Pixel Autofocus would be inevitable eventually. Several new patents have been released over the last few years, including this one from 2020 suggesting that it might come with the EOS R1. Now a new patent from Canon about Quad Pixel AF adds more fuel to that EOS R1 fire.
Dual Pixel AF is pretty awesome, as evidenced by the significant lack of auto-backfocus jokes we used to regularly hear about Canon DSLRs. And while it’s not perfect, it seems to be leading the way lately in some respects. But Quad Pixel AF should help to make Canon’s EF more reliable and accurate than it has already become, posing a serious threat to the competition.
