Abstract

PURPOSE: To attempt the enhancement of both maneuverability of a manual range finding lens and maneuverability of amnual zooming action by providing the drive transmission system by which the drive force of a camera main body is transmitted to a range finding ring within a lens barrel.
CONSTITUTION: Outer rigging which protects transmission shaft 3 and its gear 5 dispenses with by disposing the transmission shaft 3 within the lens barrel in the fixed ring 9 and the zoom operating ring 15, hence the manual operation of range finding ring 6 and zoom operating ring 15 can be done with no infliction of interruption so that its maneuverability can be enhanced. And it is necessary that the transmission shaft 3 should pierce lens mounts 12, 13 of zoom lens system, hence it is no longer reguired for guide shaft to provide it separately by fitting the transmission shaft 3 and the zoom lens mount slidably and closely each other so as to combine with the guide shaft.
