Focusing apparatus

A focusing apparatus comprising:

• a setting unit configured to set a first focus detection area to be focused among a plurality of focus detection areas;
• a memory configured to store focus correction information based on a focusing status of a focus lens in each of the first focus detection area and a second focus detection area that is different from the first focus detection area;
• a focus detection unit configured to detect the focusing status of the focus lens in the second focus detection area;
• and
• a focusing unit configured to move the focus lens for focusing based on the focusing status of the focus lens detected in the second focus detection area,
• wherein the focusing unit corrects a difference between an object distance of the first focus detection area and an object distance of the second focus detection area in accordance with the focus correction information stored in the memory and the focusing status of the second focus detection area detected in the focus detection unit, corrects the focusing status of the second focus detection area detected in the focus detection unit based on the corrected difference between the object distance of the first focus detection area and the object distance of the second focus detection area so as to focus the first focus detection area, and moves the focus lens based on the corrected focusing status of the second focus detection area.
