Abstract:
A control apparatus provided in a lens apparatus controls a plurality of optical systems each including an aperture diaphragm which is variable in aperture diameter. A lens control unit sets driving amount information regarding the respective driving amounts of the aperture diaphragms, and sets driving speed of each of the aperture diaphragms based on the driving amount information. The lens control unit determines the driving speeds of the respective aperture diaphragms such that driving times of the aperture diaphragms of the plurality of optical systems match each other.
