Abstract
A lens apparatus is disclosed which is capable of picking (taking) moving images and picking still images by using a mechanical shutter without a detector to detect the state of the mechanical shutter. The lens apparatus comprises an aperture stop, a mechanical shutter, and a lens controller which sends first information used for an electronic shutter control of the image-pickup element to an image-pickup apparatus. The first information relates to time or speed, determined according to an opening state of the aperture stop, from the start of image-pickup with the image-pickup element to the completion of closing operation of the mechanical shutter.
