发明名称 Optical apparatus with a plurality of selectable auto-focus areas within a focus-range
摘要 An optical apparatus includes a detector detecting information used for focus control in each of a plurality of detection areas set in an image-pickup area, a selecting member being operated to change a selected area selected from the plurality of the detection areas, and a controller performing the focus control based on the information detected by the detector in the selected area. The controller determines a selectable detection area among the plurality of the detection areas based on the information used for the focus control detected in each of the detection areas and changes the selected area among the selectable detection areas in response to the operation of the selecting member. The optical apparatus reduces burdens in a selecting operation of the detection area for information used for the focus control and allows selection of an intended detection area quickly.
