2. Related Background Art
Heretofore as in the refraction type telephoto lens described in U.S. Pat. No. 4,907,868, aberration correction has been effected by a first lens unit and a second lens unit, and in the other cases, only a single lens unit is used for aberration correction. These units are moved perpendicularly to the optical axis to thereby effect antivibration.
