<p>PROBLEM TO BE SOLVED: To provide a lens device, imaging device and imaging system that enable prevention of an image of low image quality from being photographed or prevention of occurrence of defectiveness upon a photograph operation by controlling timing at which an optical unit is moved.SOLUTION: A lens device has: an imaging optical system that is attachable/detachable to and from an imaging device, and forms an optical image of an object; an optical unit that moves so as to insert and retreat to/from an optical path of the imaging optical system and thereby makes an optical characteristic of the imaging optical system different; and lens control means for limiting the movement of the optical unit. The lens control means is configured to receive information indicative of a photograph state of the imaging device from the imaging device, and limit the movement of the optical unit on the basis of the information indicative of the photograph state.</p> |
