An electronic device communicates with a lens unit whose focus range is a first range between a first position and a second position of a focus lens. The electronic device obtains first information indicating a third position of the focus lens, at which the focus distance of the lens unit infinity, and a second range between the third position and the second position of the focus lens. The electronic device controls, on the basis of the first information, a display unit to display the first range and the second range of the focus lens to be distinguishable from each other.
