Something happened and I can no longer use AF on my camera and lenses. It used to work for both my Canon 11-24mm f/4 L and the Canon 24-70mm f/2.8 L II, connected to my Sony A7RII via the Metabones IV adapter. I have tried reseating the adapter and the lenses. Of course I've checked to make sure the AF switch is turned on, flipped it back and forth a few times. In my settings menu (page 3) for the camera when I click on Focus Mode it says "Invalid with this lens. If the lens has an AF/MF switch, perform the operation from the lens." I am using back-button focusing, where when you flip the AF-MF switch up the AEL button will can change between using AF and MF assist, and when it is switched down the button executes either AF or the MF assist.
I was able to use AF in the past on both lenses. I recently upgraded the Sony firmware, to version 3.20. I can't remember if the problem began before or after that upgrade however, as I do like to shoot in MF a bit, but these are expensive pieces of equipment and AF is nice to use when you want it.
Any thoughts on what I can do to resolve this issue? When I check the Sony firmware version it is reporting that the lens is version 47. But I don't know if that is for the lens or the adapter. I'm not certain how to check or upgrade the Metabones adapter's firmware, but I do know that the Metabones IV is firmware upgradable. So that is something I do want to look into, I just need to learn how to do it.
Has anyone else experienced a loss of AF functionality when upgrading the Sony A7RII to firmware v3.20?
Thanks for any help or advice.
