Shoot low-light sport with a high ISO

13A combination of low light and high-speed action calls for a high ISO. Not only do you need a high enough ISO for faster shutter speeds to ensure you can handhold the camera without images suffering from camera shake, but one fast enough to freeze fast action. Many sports are played in the evening under floodlights or indoors, which makes an ISO of 3200-12,800 a common requirement to achieve shutter speeds around and in excess of 1/500sec. This high ISO is often combined with a fast telephoto lens with a maximum aperture of f/2.8, and a camera that has excellent high ISO performance.
