摘要：
A diaphragm linkage device for interchangeable lenses wherein more than three column-shaped guide members with a groove consisting of plastic material with a small friction coefficient are provided around the optical axis of the barrel for the interchangeable lens. A diaphragm linkage ring is adapted in the grooves in such a manner that by means of the guide members the diaphragm linkage ring is carried in the direction of thrust and in the radial direction.
