1. An image capturing apparatus comprising:
an operation member used to move a position of focus lens included in an attached optical system;
a recording unit that records the position of the focus lens as an index value in a memory in association with information of the attached optical system including the focus lens in response to a registration instruction;
an acquisition unit that acquires information for identifying the attached optical system;
a readout unit that, if there is an index value recorded in association with the information of the attached optical system corresponding to the information acquired by the acquisition unit, reads out the index value from the memory;
a control unit that controls a display device to display the read index value and a current position of the focus lens; and
a determination unit that determines accuracy of the index value recorded in association with the information of the attached optical system,
wherein the control unit controls not to display the read index value on the display device in a case where the accuracy determined by the determination unit is lower than a predetermined accuracy, and
wherein the recording unit, the acquisition unit, the readout unit, the control unit, and the determination unit are implemented by one or more processors and/or circuitry.
