The 180mm f/4 VSF lens is a compact mid range telephoto lens. It
yields a good camera to subject distance, slight flattening of portrait
subjects, and exceptional sharpness.
The unique optical design essentially has an "optically correct
center," which can produce a sharp image virtually equal to a standard
180mm lens, when an aperture of f/8 or smaller is used. The edges of the
lens elements are designed to induce "spherical aberration," which
creates a dreamy, soft focus effect when the lens is used at apertures
wider than f/8. Unlike common soft focus attachments that simply degrade
a sharp image, the RZ 180mm VSF can "build" a soft focus image using
its unique combination of spherical aberration and diffusion disks. The
result is tremendous creative control for effect from dramatic to
subtle.
Three supplementary disks are supplied with the lens, and fit
internally in the lens barrel. The three disks are labeled No.1 (5),
No.2(5.6) and No.3 (6.3). The numbers in parentheses are the approximate
f/stops to which the lens diaphragm, when set to f/4, is modified. The
disks, numbered one, two and three, have different diameter holes in the
center, surrounded by numerous smaller holes extending toward the edges
of the disks. These small holes act like multiple diaphragms,
overlaying softer images on top of the sharp image projected through the
center hole. The overall level of sharpness is controlled by the
diaphragm opening and choice of disk. Also, whether or not a disk is
used at all.
