RF Mount protocol is not open to third party companies means Sigma need to do reverse engineering in order to produce RF Mount lenses, I guess it would be just simply convert the EF Mount to RF Mount lenses by changing the lens barrel.Is Canon now open like Sony to give Sigma what they need with proper communication and software so that the Sigma can have equally good AF? If not I wont buy Sigma glass, no matter how good or cheaper it is. Thats almost just me though, and I wont likley buy more than a 24-105, tele like 100-400 or 70-200, a wide angle and maybe a fast prime. All for video. But yes, competition is always great.
