Autofocus lens for
macro photography up to life-size (1x) magnification

Medium telephoto lens with a macro
feature for 1x magnification. Fluctuations in spherical aberrations
caused by focusing are suppressed, and high-quality images are
obtained at all focusing distances. With eight aperture blades, good
background blur is obtained even when the aperture is decreased by
one or two stops. A focusing limiter which limits the magnification
to 0.25x is built-in.
KEY FEATURES
-
Entirely new
optically, with a three-group floating system for exceptional
close-up performance.
-
The first lens in
its class to feature innner focusing. The lens length never
changes, even at life size!
-
A secondary
diaphragm blocks stray light at f/2.8, increasing contrast when
shooting wide-open.
-
Ultrasonic Motor
provides outstanding AF speed at all focusing distances.
-
Wide manual focusing
ring with smooth action, and full-time manual focus even in AF
mode.
