In bright sunlight you need 1/6400 seconds at f/1.4. Any reduction in sunlight requires a slower shutter speed. At f/1.2 you are looking at 1/8700, but how often are you going to encounter this situation? Now stopping a bullet in midair, or totally freezing a humming birds wings might require a much shorter shutter speed, but if this is what you are shooting, you have the wrong camera, or need flash.
