This feature in invaluable when shooting into the sun or other back-lit situations. Bright f1.8 Aperture A bright f1.8 aperture allows you to focus on getting the shot. Whether you're shooting in a dimly lit restaurant, or capturing a night-scene on city streets, you won't have to worry about having enough light.
