How to Take Indoor Sports Photographs
Lighting is very critical with indoor sports. Pick your lens with at least at f/2.8 aperture or greater. An 85mm f/1.8 lens, especially on a 1.6 sensor body, can take good photographs in low levels of light. The image stabilizing can help while hand holding the lens, but having a large aperture is a lot more important while taking indoor action photographs to freeze your subjects with a faster shutter speed. You can always use a tripod for camera shake. Use faster ISO speed settings to freeze the action.
Telephoto lenses usually don’t have a large aperture. The ones that do are very expensive. This is the advantage of a 1.6 size sensor. A 200mm f/2.8 lens is now a 320mm f/2.8 lens with the same aperture and the same price!
