PROBLEM TO BE SOLVED: To simplify setting operation, to improve operability and to reduce cost by selectively switching 1st and 2nd AE lock modes, and using the same AE lock button in common between the 1st and the 2nd AE lock modes. SOLUTION: The 1st AE lock mode (BV value lock) and the 2nd AE lock mode (control value lock) are selected by the depressing operation of a custom button 6 with the operation of a main command dial 3 and further the operation of a sub command dial 4. When the AE lock button 7 is operated to be depressed, the BV value of the photometric device of a camera is stored in the 1st AE lock mode; a shutter speed value (TV value) and a diaphragm value (AV value) calculated by a program based on the BV value being the result of photometry by the camera and ISO sensitivity information of film are stored in the 2nd AE lock mode; and the diaphragm value is stored in the case of program automatic exposure; and the shutter speed value itself is stored in an aperture-priority mode. |
