I guess it's all about Interpretation, but they say improved.
Maybe you've all seen this, but if not, go to the 5:50 mark. Just another video ( a rough video ) but Matt Frazer speaks on the auto focus the same way he has in every video I've seen, but says it's "Auto focus system is on steroids" I understand marketing hoopla, but based on the consistent claim that the auto focus is a major improvement up from the GH4 I'm expecting a solid auto focus improvement, if not Matt, and Lumix will have told blatant lies. He addresses the GH4 every time they discuss auto focus and acknowledges that it was a area to improve going off of user feedback.
