Description

FIG. 11 is a lens configuration diagram of the imaging optical system according to Example 3 of the present invention. In FIG. 11 , L1 is the first lens group, L2 is the second lens group, L3 is the third lens group, L4 is the fourth lens group, L5 is the fifth lens group, S is the aperture stop, I is the image plane, F Is the filter, and the alternate long and short dash line through the center is the optical axis.
FIG. 16 is a lens configuration diagram of the imaging optical system according to Example 4 of the present invention. In FIG. 16 , L1 is the first lens group, L2 is the second lens group, L3 is the third lens group, L4 is the fourth lens group, L5 is the fifth lens group, S is the aperture stop, I is the image plane, F Is the filter, and the alternate long and short dash line through the center is the optical axis.
The fifth lens unit L5 have a biconcave lens, and a positive meniscus lens having a convex surface directed toward the object side with an aspherical surface on the object side, a positive refractive power as a whole. The fifth lens unit L5 moves toward the object side during zooming from the wide-angle end to the telephoto end, and draws a trajectory that is farthest from the image plane in the middle region of the lens.
