Eye-Start AF

[Hamid.K]

Hi All.

Today I updated my A7R4 firmware to 1.20. After that on the menu, the Eye-Start AF is grey out and when I click on it, a pop-up message says that "it is not valid with this lens". my lens is new 85mm Sigma 1.4 DG DN and before the update, the menu was white and I could select Eye-Start AF. however, still, the eye AF is working. does anybody have any idea? I appreciate your help. Thank you

ps. I took the battery out and put it back and detached the lens and re-attached again.No changes.
