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.
