Hi! I’m having issues trying to adjust lens focus with the “Move the focus” arrows. I’m using a Sony ZV-E10 camera with a Tokina FiRIN 100mm lens.

With the same camera but other lenses, this feature works reliably. But with the Tokina lens, sometimes it moves when I press an arrow, sometimes not. I’d like to use some code to set focus to a particular distance, so this is a problem if I can’t count on the lens responding to each and every “move” command.

Has anyone else had issues with Tokinas?
