I just picked up that camera in a local camera store. What a mistake that was. That camera was built with me in mind. I've seen the pictures and did comparisons to my GH3 before I bought it, but man, having that little gem in my hot little hands is something else! The lens (12-50mm) even has a motorized zoom which is butter smooth and speed sensitive. I love what my GH3 can do, especially for video, but THAT is a camera my friends. Now I see what all the hype is about. I pretty much ran out of the store, got out the calculator when I arrived home to see when exactly it is I can bring the new baby home. Middle of next week, can't wait. My GH3 is gonna be collecting some dust soon sheesh. If anyone is still reading and can answer...will it auto focus my Panny-Leica 25mm? If so, will it do it as well as my GH3? Are there any major drawbacks to using Panny lenses? Thanks.
