At such a time, the part of the panel 14 on the inside of the finder where the light control correction quantity is displayed is in a bright display state similarly to the case of other information. Meanwhile, when the camera is in the FE lock state, an inverting command on the display of the light control correction quantity is transmitted to the circuit 3.
