摘要： The lens apparatus according to an aspect of the present invention includes: a focus lens which is driven for bringing a desired subject into focus; a zoom lens which is driven for changing a focal length; and a diaphragm having an aperture diameter which is changed for adjusting an amount of photography light, and the lens apparatus is configured to adjust a position of the focus lens, to thereby perform flange back distance adjustment. In such a lens apparatus, the aperture diameter of the diaphragm is changed at a time of mode transition between a photography mode in which a normal photographing operation is possible and an adjustment mode in which the flange back distance adjustment is possible. Accordingly, the user can instantly know whether or not the lens apparatus is in the flange back distance adjustment mode, only by checking a video picture photographed by a television camera.
