had to get a GH2 because the size of the G3 just didn't fit my hand. Very good camera otherwise.. Kudos to B&H for letting me exchange it at 31 days. They didn't have to but did. I also picked up a FZ150 for my wife and kids to use daily. I need recommendations on SD cards for video. I have heard various things from a Class 4 is sufficient to you need a class 10. So which is it really?
