Claim:
1. An imaging apparatus, comprising a lens unit having a photographing optical system, and a body, to which the lens unit can be attached, having an image sensor for generating a pixel signal by imaging subject light that has passed through the photographing optical system, wherein: the lens unit comprises an aperture which restricts light flux that passes through the photographing optical system, a zoom control section which adjusts focal length of the photographing optical system, and an aperture control section which controls opening of the aperture, and the body comprises an exposure control section which adjusts exposure amount for image data based on a pixel signal generated by the image sensor, by transmitting an aperture control signal to the aperture control section and changing opening of the aperture, and a determination section which determines whether or not the aperture control section is able to control opening of the aperture based on information from the lens unit, wherein the exposure control section does not transmit aperture control signals to the aperture control section when it is determined by the determination section that the aperture control section is able to control opening of the aperture.
