Abstract

PURPOSE: To obviate mutual interference of a manual operating member and automatic operating member by providing a suppressing means which suppresses the other member to the close distance focus position or infinite focus position of itself when either of the members is selected.
CONSTITUTION: There are three helicoid barrels, an outer helicoid barrel 13, middle helicoid barrel and inside helicoid barrel 17. The barrel 15 and distance setting ring 11 are held coupled. Further the cam face and concave face with which a set distance detecting member 31 and automatic focus detecting member 33 make contact are provided to the rear end face of the ring 11. The barrel 13 is secured to a stationary ring 21 and a rectilinear propagation key 19 is secured to the barrel 17. By changing over a manual-automatic focus setting changeover ring 26 to either automatic or manaul, either manual or automatic foucs setting is accomplished and always desired focus controlling is accomplished without mutual interference of the manual operating member and automatic control member.
