发明名称 MANUAL FOCUSING MECHANISM OF IMAGING APPARATUS, AND THE IMAGING APPARATUS
摘要 PROBLEM TO BE SOLVED: To provide a manual focusing mechanism of an imaging apparatus for performing focusing easily even while the visual recognition of the focusing state is restrained.SOLUTION: The manual focusing mechanism of the imaging apparatus linearly moves a focusing lens in an optical axis direction thereof via a manual operation of a focusing operational member. The manual focusing mechanism includes a focus click mechanism for holding the focusing operational member at a plurality of click positions with respect to a support member. An amount of movement of the image plane position per one click of the focusing operational ring via the focus click mechanism is determined to be within the depth of focus of an imaging optical system.
