EPL5 AF tracking seems usable
I own the E-PL5 too, and I can tell you the tracking is not good for sports. Remember, with the car and the man on the bicycle (whose face is still somewhat out of focus in your photo or at least noisy), you know exactly where they are going in a straight line. You can't do that with soccer. In addition to coming toward you, they are zig-zagging a lot. When I used my camera to track soccer players, it did track them well, but the focus was never tack sharp. It's best to use single AF for situations like this. The on-screen touch autofocus/shutter is an intriguing option.
