Abstract

See full text

When the lens barrel is in the storage state, a part of a lens group and a group cylinder are inserted into an aperture of a diaphragm unit and a shutter blade of a shutter unit is closed for light shielding. With this arrangement, the cylinder length in the storage state is shortened, and the performance degradation of an image sensor and optical components provided on a front side of an image sensor can be prevented as well.
