ABSTRACT:
The invention is directed to a focusing mechanism that provides additional focal movement of the lens system without increasing the depth of the camera. This is accomplished by a bearing connected to lens mounting unit that is slidable along a guide shaft, because a part of the bearing can enter a recess in a support on the main body of the camera.
