This and the following 2 shots are once again sequential using the FZ30's high burst mode. The red dot made tracking a cinch, and the focus stayed "locked on" throughout. The camera settings that seem to work best for me are a high shutter speed of around 1/1000 sec, f4.0 depending on the sunlight (these were taken in late afternoon),and High-Speed 3-area focusing where the camera focuses on any 3 areas in a straight line across the viewfinder. I try to verify that the bird is "locked in" at the beginning to ensure continued sharp focus throughout the sequence.
