Abstract:
A zoom lens having an image stabilizing function, comprising, from front to rear:a first lens unit of positive refractive power; a second lens unit of negative refractive power; a third lens unit of positive refractive power; a fourth lens unit of negative refractive power; a fifth lens unit of positive refractive power; and a sixth lens unit of negative refractive power, wherein said second lens unit is stationary during zooming, and zooming is performed by varying separations between said lens units, wherein said second lens unit is made to move in a direction substantially perpendicular to an optical axis so as to correct shaking of an image, and wherein said zoom lens satisfies the following condition: 0.150.5 â€ƒwhere fa is the focal length of said second lens unit, and fW and fT are shortest and longest focal lengths of said zoom lens, respectively.
