ABSTRACT:
A zoom lens includes, in order from as object side, a first lens unit having a positive refractive power, a second lens unit having a negative refractive power, a third lens unit having a positive refractive power, a fourth lens having a positive or negative refractive power, a fifth lens unit having a negative refractive power, and a sixth lens unit having a positive refractive power, and a sixth lens unit having a positive refractive power, wherein the separations between the lens units are varied to effect zooming. Further, the fifth lens unit is arranged to move in directions substantially perpendicular to the optical axis to compensate vibrations.
