FIG. 3 is a schematic diagram illustrating an example of the configuration of a binocular lens unit 300 as an example of a multi-scopic lens unit. In the present specification, “multi-scopic lens” refers to a lens unit constituted by a plurality of imaging optical systems within a single lens mount (or lens barrel), and which has a plurality of optical axes. FIG. 3 illustrates the binocular lens unit 300 mounted to the camera 100. In FIG. 3, only part of the configuration of the camera 100 illustrated in FIG. 2 is illustrated.
The binocular lens unit 300 is a type of interchangeable lens that can be attached to and removed from the camera 100. The binocular lens unit 300 has two imaging optical systems 301L and 301R in one lens barrel, and thus has two optical axes.
