摘要:
A zoom lens includes a function of preventing blurring of an image due to movements, such as shaking of the zoom lens, by moving the second lens group, in order from the object side, orthogonally to the optical axis in order to correct for blurring of an image due to movements of the zoom lens. The zoom lens includes a first lens group having negative refractive power, a second lens group having positive refractive power, and a third lens group having positive refractive power. The first and second lens groups move along the optical axis during zooming, as does the third lens group in all but one embodiment of the invention. The zoom lens satisfies certain conditions related to the configuration of the lens elements and lens groups of the zoom lens in order to prevent blurring and to provide a compact zoom lens having excellent correction of aberrations.
