The autofocus of the Olympus is rather slow, and from what a friend shared doesn't follow the subject well. In other words, the camera struggles to stay in focus if the object is moving. I recently purchased a Gf1 with the 20 1.7 lens, and have been very pleased with it. The focusing speed is reasonable, and does alright at following moving objects.... Usually. I haven't had it long enough to tell you how well it does in every situation. I've been using it primarily as a point and shoot, and not as a video cam. If your goal is primarily video, then you might be better off with a low end canon or panasonic hd camcorder.
