An image taking apparatus has a solid-state image-sensing device, a shutter
for shutting off the light incident on the solid-state image-sensing
device, and a zoom optical system. The optical aperture stop of the zoom
optical system and the shutter are located both on the optical axis but at
different positions. During zooming, while the optical aperture stop moves
along the optical axis, the shutter is kept stationary. The zoom optical
system has an optical member having an optical power disposed on the
image-plane side of the shutter.
