Abstract: In a digital camera, a solid state imaging device is used to catch subject light so that an image signal is created. The digital camera contributes to effectively implementing further thinness in such a manner that a part of image taking lenses is saved to a suitable position at the time of the collapse. Both the rear elements lens and the focus lens are revolved between a position on the optical axis and a saving position coming into a hollow portion beside the CCD solid state imaging device, or between the position on the optical axis and a saving position in which the front elements lens, the rear elements lens and focus lens form a line substantially on a plane.
