OPERATION DEVICE, OPTICAL DEVICE, AND IMAGING APPARATUS

To provide an operation device advantageous for fine adjustment of the optical characteristics of a lens device.SOLUTION: An operation device (10) for controlling a movable optical element for adjusting optical characteristics of a lens device, includes: an operation member (101); a detection part (102) that detects the operation amount of the operation member; and a processing part (106) that generates a command on the basis of the relationship between operation amount and command, in which the operation sensitivity as the ratio of change of command for controlling the operation amount is not constant. The processing part changes, with respect to the current operation amount of the operation member, the operation sensitivity from a first sensitivity to a second sensitivity lower than the first sensitivity on the basis of the relationship.SELECTED DRAWING: Figure 3 【課題】 レンズ装置の光学特性の微調整に有利な操作装置を提供すること。【解決手段】 レンズ装置の光学特性を調整するために可動の光学素子を制御するための操作装置（１０）は、操作部材（１０１）と、操作部材の操作量を検出する検出部（１０２）と、操作量の変化に対する、制御のための指令の変化の割合としての操作感度が一定でない、操作量と指令との間の関係と、操作量とに基づいて、指令を生成する処理部（１０６）と、を有する。処理部は、該関係に基づいて、操作部材の現在の操作量に関して、操作感度を第１感度から、該第１感度より低い第２感度へ変更する。【選択図】 図３
