An image capture apparatus sets a first value relating to an aperture diameter, and performs display control when displaying on a display unit a plurality of settable first values including the first value currently set in the image capture apparatus. The image capture apparatus controls such that, when a first range in which changes in the first values and changes in second values indicating a lens brightness that are different from the first values are proportional and a second range in which the changes in the first values and the changes in the second values are not proportional are present as the plurality of settable first values, the changes in the first values are displayed discretely in the second range with reference to the changes in the second values.
