Abstract
An appropriate operation angle (actuation angle) corresponding to a use is obtained by a relatively simple structure. A focus ringis mounted around a focus camWhen the focus ringis moved to a front end side, a gear formed in the focus ringmeshes with a gearof the focus camand the rotation of the focus ringis directly transmitted to the focus camWhen the focus ringis moved to a rear end side, the gear formed in the focus ringmeshes with pinionsmounted on the focus camand the rotation of the focus ringis directly transmitted to the focus camthrough the pinionsA half of the rotation angle of the focus ringis the same as the rotation angle of the focus cam
