My first m43 camera was the Olympus EP1. I bought it because I didn't want to carry my D700 for taking picture casually. It was small, light and did the job. But I ended up selling it and with with a smaller system, a PnS, the Olympus XZ-1. Last night I pulled the trigger on the Panasonic GH2 for $499 off of bhphoto.com. They had free overnight shipping so I took advantage of that. This time around I will use it mainly for video. Many users raved the camera's video ability after you hacked it. As a professional photographer, video is something that I can't ignore anymore.
