The present disclosure is directed to preventing an operation from being performed in an operation mode that is not intended by a user. In an image capturing apparatus, a moving image lever is an operation member for issuing an instruction to change an operation mode to a moving image capturing mode that is a state where a moving image is recordable. In order to avoid unintentional change of the operation mode to the moving image capturing mode due to an erroneous operation on the moving image lever, a setting is made to enable and disable an instruction that is issued by operating the moving image lever. If the setting is changed to 'disable' while the image capturing apparatus is operating in the moving image capturing mode, a microcomputer changes an operation mode to a still image capturing mode.
