Last July I attended a Red Sox home game at Fenway. Our seats were on the roof level, halfway between first base and the home run pole. The speed of the action required shooting at 1/1024 second. It was an evening game under the lights, so I had to shoot at ISO 1600 in order to get good exposure at f/5.6.
This first shot shows Jacoby Ellsbury hitting a home run. The ball actually hit the home run pole. Of all the shots I took, this was the only one where I captured the ball on the bat. The original image has been cropped about 50%. I was about 250 feet away from home plate.
Later in the game, Josh Reddick tracked down a fly ball in right field. This one was shot at ISO 3200 using 1/640 sec, hence the graininess. Overall, I'm pleased with the quality of both these shots given the level of light and the speed of the action.
