Abstract:
PURPOSE: To prevent a desired picture angle from being changed even when focusing is implemented after the desired picture angle is set.
CONSTITUTION: A master lens 21 is moved in a lens system 8 to implement focusing. Since only the master lens 21 is moved for the focusing, the mutual positions of another lens systems such as a front lens group 12 and a zoom lens system 15 are not deviated. Thus, the magnification of the zooming is unchanged and the picture angle is not deviated.
