description A teleconverter includes a master lens apparatus-side mount on which a master lens apparatus is mounted, a camera body-side mount on which a camera body is mounted, and a converter lens unit that has a negative refracting power for mounting the master lens apparatus thereon to obtain a lens system having a focal length longer than that of the master lens apparatus, the converter lens unit including a first lens group on the master lens apparatus side and a second lens group on the camera body side with an on longest air separation interposed between them, the first lens group has positive refracting power, and the second lens group has negative refracting power, with satisfaction of the following condition (1): -1.53
