Aperture settings can range from a pinhole-like f/64 to an eye-popping f/1.8, f/1.2 or (gasp!) even larger. As the light level grows dimmer, the need for ever wider lens apertures increases. Fast action sports like formula auto racing, horse racing, power boat competitions or team blitz action as experienced in ice hockey, basketball and other indoor court sports require careful consideration of lens apertures used for taking pictures of sports. Remember though, the wider or larger the lens aperture the narrower the depth-of-field range of the image.
