<P>PROBLEM TO BE SOLVED: To provide a lens barrel adapter, a lens barrel and an imaging apparatus using the same, which are able to reduce fatigue of a user and pick up a stereoscopic image allowing a user to enjoy pop-up feeling and depth feeling, by decreasing the angle of convergence to 3 degrees or less in a close distance. <P>SOLUTION: The luminous flux 300 of a subject is taken into a second lens system 120, which is a zooming lens system, and a fourth lens system 140, which is a focusing lens system, via a first lens system 410 for an adapter arranged on a first optical axis and via a second lens system 420 for an adapter arranged on a second optical axis. An angle of view on the first optical axis and an angle of view on the second optical axis, which are determined by the lens barrel 100 after the lens adapter 400 is attached and by the lens barrel adapter 400, are made wider than an angle of view determined by only the lens barrel 100 before the lens barrel adapter 400 is attached. <P>COPYRIGHT: (C)2013,JPO&INPIT |
