Yeah the new autofocus system is actually a huge deal. Autofocus on the GH6 was super bad, I don’t know why the guy said it’s just a small update. The autofocus was the most crippling aspect of the GH6
I think a lot of Panasonic Lumix users tend to use manual focus with mechanical manual focus cinema lenses and those who use single auto-focus won't be affected of the problems with the lack of PDAF for continuous AF.
