I know you believe what you say. OTOH the folks who pay the mortgage with their cameras use the latest and greatest autofocus, autoexposure, auto ISO. They do not have the luxury of dawdling with their camera to express themselves. They need the picture. You cannot focus faster than autofocus, you cannot set exposure faster than autpoexposure, because you cannot think faster than a computer. This is fact. If you really believed you could you would be full manual, wouldn't you?
So it comes down to personal choice and just how much "control" you wish to exercise over your photos. Factor in your hit rate. How many are in focus? If you do not use autoexposure, how many are correctly exposed? Current Japanese autofocus is amazingly fast and amazingly accurate. Check out the wildlife telephotos here (
