Abstract
A retractable photographic lens including a photographing optical system includes a plurality of optical elements including at least two radially-retractable optical elements; wherein the plurality of optical elements are aligned with an optical axis in an operating state of the retractable photographic lens. When the retractable photographic lens moves from the operating state to a fully retracted state, the two radially-retractable optical elements of the plurality of optical elements are radially retracted to respective radially retracted positions thereof away from the optical axis in different radial directions and moved rearward in the optical axis direction to be positioned adjacent to each other in a plane orthogonal to the optical axis.
