I don't think I agree w/ this.. I'd say within the last year or two...the Panasonic auto-focus has taken a huge leap, especially in video auto-focus. It might not be as good as Canon, but I would say it's pretty on par, neck and neck w/ Sony. I've never shot Nikon for video, so I don't know but...Panasonic is right there, and definitely ahead of Fuji auto-focus for video. I didn't start using auto-focus on video until 2024, and the sole reason why I started was because the S5ii + recent update made it so. It is spot on. Game-changer for me. By this time next year...it'll be doing whatever Sony and Canon do, for sure. If not better.
