Does Canon 6D MFA work for 35/1.4 ART?

The super secret Canon autofocus SCANDAL

The skeptic in me now thinks that as a Canon body can detect which lens is mounted and provide a Canon profile, perhaps it can also detect 3rd party glass and throw a random focussing spanner into its focussing algorithm.

Ok I thought about this. And I definetely think you are on to something. Software wise it would be trivial to do. And the way you are describing it has exactly the DNA of a software glitch. And there are LOTS of people reporting the same inconsistency problem.

Canon got away with it, because people attributed this behaviour to clunky reverse engineered AF protocols. And BOTH explanations might be right, suppose Canon has set a sort of randomizer "trap" in their AF protocol and only for proven Canon gear the trap is avoided. You could call this "incomplete reverse engineering" if you didn't know about the trap. Could they actually be sued for dirty tricks like this or are they in their rights?

The journalist in me has awakened: what if some clever Magic Lantern programmers put one and the same sigma 35/1.4 on a 6D body and somehow software-wise FAKE to be a Canon lens, I mean these people are hackers. And suppose problems are completely gone. And with the fake ID removed the problems return. Now THAT would be a big scandal wouldn't it? Thousands of Canon customers completely sabotaged for not being 100.00% loyal.

Kind regards,
