The faster the shutter speed on a camera the more light it needs from the lens to give you a picture; and or the ASA/ISO (film speed numbers) needs to be cranked up, it then adds "grain" to the picture.
With today's ~$6000 cameras and a F1.8 135mm $1500 on a sunny day why would you need to run at such a high speed when you could get a more clear and better picture going slower.
