Never said it was the answer to everything... Obviously you need to have enough shutter speed to stop the subject motion if the subject is moving...even when panning. But I understand the OP's question and the tripod would be the most universal answer without getting into all the various focusing nuances of say Nikon lenses.

A tripod isn't the answer to everything. It only works to prevent camera motion, so if you are shooting moving subjects, you will still have to use a high enough shutter speed to stop the action.
