Abstract:
An image pickup apparatus and a lens apparatus capable of photographing high-grade still images even where an interlace type image pickup element is used are to be provided. When an instruction to photograph a still image is entered, a camera microcomputer generates a timing to intercept light coming incident on a lens according to the aperture value of an iris, and transmits this timing to a lens microcomputer. The lens microcomputer supplies a control signal to an aperture control circuit according to the received timing, and a mechanical shutter is caused to operate as the aperture control circuit closes the iris at high speed.
