摘要:
A zoom lens has a first group of a positive refractive power and a second group of a negative refractive power in sequence as seen from an object. The first group of the positive refractive power comprises a front group of a positive refractive power arranged to face the object and in front of an aperture iris and a rear group of a positive refractive power arranged between the aperture iris and an image plane. The rear group includes displacement means to drive it across an optical axis for vibration correction.
