This weekend I was asked to photograph our neighbor's dog Casey. She's quite energetic and we went to a nearby park and I just a series of shots with her running after a tennis ball. This was also a good chance to work out the 1D3's ability to track a large fast moving target. Overall I am impressed with the keeper rate and the AI Servo tracking abilities of the 1D3.
Technical Specs: Canon 1D3, 200 f/2 IS, f/2.8, ISO 400, varying shutter speeds.
