I’m using a Canon R5 camera with Canon rf 100-500 lens. I Shoot in Manual mode. In AF menu 4, I cannot set the option “Stop Focus search to ON”. The option is there in the menu and it is NOT grayed out. When I select it and press the set button it goes back to the menu 4 list with the “Stop Focus search to ON” set to Off. The camera does not indicate that any other setting is preventing the option from being set. I have tried setting the option in TV, AV and Manual and it doesn't work in either.
My Operating system is the current version of windows 10.
Thank you for your assistance.
