An electronic device comprises a rotational operation member and a control unit that controls an angle of rotation at which to generate a clicking sensation in the rotational operation member. The control unit controls the angle of rotation based on a division of a setting to be changed in accordance with a rotational operation of the rotational operation member.

A rotational operation device that is capable of setting an operation mode corresponding to a user's intention even when rotation of a rotational operation member stops on the way during a rotational operation. A rotational operation member is rotatable around a rotation axis. A click force application mechanism applies click force to the rotational operation member according to its rotational operation. A detection unit detects rotation of the rotational operation member. A setting unit sets one operation mode from among a plurality of predetermined operation modes in response to a detection output of the detection unit. The setting unit switches the operation mode according to a rotational operation of the rotational operation member before a position where the click force applied to the rotational operation member by the click force application mechanism becomes zero in a case where the rotational operation member is rotated in a first direction.
