A telephoto lens is essential to any serious photographer. For sports action, you will need a fast shutter speed and a long focal length. A large maximum aperture allows a faster shutter speed. In this telephoto lens line-up, the focal lengths range from 135mm to 300mm. If you want compactness, choose a lens with a smaller maximum aperture.
