Oh, Panasonic 100-300mm f/4.0-5.6! You are such a zoomy lens yet no bigger than a can of soda. You reach across the soccer pitch so easily and throw the background mildly out of focus. And you lend a hand in holding steady. So nice, so nice. But slow to focus. You miss a lot of the action. Or should I blame your partner, the GH2?
