description The present invention relates to a lens mount assembly for use in photographic camera, video camera and other various optical instruments. Usually, electric drive units for focussing and zooming, respectively, are gear-coupled to such lens mount assembly and drive torque from these drive units often causes deviation, deflection and eccentricity of the lens mount assembly, and additionally causes unreliable gear-coupling of the drive units and deteriorated image forming capability of the optical systems. The present invention provides a barrel supporting mechanism adapted to slidably support a front section of the lens mount assembly in order to overcome these problems. The present invention further provides the lens mount assembly with a simplified dust-proof mechanism utilizing a floating ring.
