ABSTRACT:
A retractable lens system includes a plurality of optical elements. All of the plurality of optical elements are positioned on a common optical axis when the retractable lens is in use. A removable element of the plurality of optical elements is moved to a removed position outside of the common optical axis, and the removable element and at least one element of the remaining elements of the plurality of optical elements are moved rearward, respectively, when the retractable lens system is in a retracted position.
