Abstract
PURPOSE: To provide always the finest aberration performance within the using angles of view changing along with shift amounts by producing fluctuations of astigmatism in the lens system and setting the variable air sapcing of less effect on other aberration fluctuations.
CONSTITUTION: The first auxiliary barrel 6 is extended straight by the action of a double helicoid 4 and straight key 5 upon the stationary barrel 1 mounted to the camera by a lens-mounting mount 2, whereby focusing is accomplished. A main lens barrel 9 is vertically shiftable with respect to the second auxiliary barrel 7 and the second auxiliary barrel 7 is shiftable in the direction perpendicular to the plane of the figure with respect to the first auxiliary barrel 6. When the shift amount of the main lens barrel 9 with respect to the first auxiliary barrel 6 is zero, it is in alignment to the central axis of the driven pin 13 but when the main lens barrel 9 is shifted, the inner barrel 11 is shifted in the optical axis direction with respect to the main lens barrel 9, thus the air spacing between lens elements L2, and L1 may be changed according to the amounts of shift.
