video pan heads normally have such a pin. the pin is ineffective on still cameras because they don't have a matching hole for the pin. instead, they have evolved a variety of solutions, all involving lots of money. an Acra-Swiss quick release system with Kirk mounting brackets is probably the best you can get. each camera has a specific bracket that holds the entire camera from tilting. if your lens has its own mounting socket, you may be able to get a bracket just for that lens.
