Abstract:
A lens barrel comprising: a main body frame; a first moving frame holding a first lens group and moving in an optical axis direction with respect to the main body frame; and a second moving frame holding a second lens group, which constitutes a fixed-focus lens in combination with the first lens group, and moving in the optical axis direction with respect to the main body frame, in which said first and second moving frames are moved by a single motor in the optical axis direction so as to provide collapse and extension with respect to said main body frame,wherein in an extension state of said lens barrel, said first and second moving frames move in one united body in the optical axis direction while keeping a predetermined interval therebetween, and in a transitional process from the extension state to a collapse state, a mutual interval between said first and second moving frames is narrowed.
