Fixed/Mounted Gear Crank (Push-Pull / Engage-Disengage Style): This style mounts directly onto the fixed lens barrel using three screws. It features an internal gear hub that meshes with the gear teeth on the zoom control ring. You typically pull the crank out to engage it with the zoom gears (which often has a slip-clutch mechanism so it yields safely when hitting the end of the travel) and push it in to disengage it so it dangles loosely out of the way
