Interchangeable lens operable in reduced power modes, image capturing apparatus and storage medium storing control program

An interchangeable lens detachably attachable to an image capturing apparatus, the interchangeable lens comprising:

• an electronic display configured to display information;
• and
• a lens controller configured to control an operation of the interchangeable lens,
• wherein the lens controller is configured to be capable of setting an operation state of the interchangeable lens to (a) a normal operation state in which the interchangeable lens communicates with the image capturing apparatus and displays the information on the electronic display, (b) a first low power consumption state in which the interchangeable lens displays the information on the electronic display with a power consumption of the interchangeable lens lower than that in the normal operation state, and (c) a second low power consumption state in which the interchangeable lens does not display the information on the electronic display and the power consumption of the interchangeable lens is lower than that in the first low power consumption state;
• and
• the lens controller transfers the operation state from the normal operation state to the second low power consumption state via the first low power consumption state in response to receipt of a power lowering instruction from the image capturing apparatus for lowering the power consumption of the interchangeable lens.
