Description
The Sigma
50mm f/1.4 EX DG HSM Autofocus Lens
is a standard lens that provides a large
maximum aperture of f/1.4. It is the
ideal prime lens for use with all Nikon
digital or film SLR cameras. When used
on Nikon digital SLR cameras with the
APS-C size sensor, the equivalent focal
length of this lens will be 75mm, which
makes it an excellent choice as a bright
short telephoto lens. Its large f/1.4
aperture allows for sharply defined
contrasty images against a nicely
blurred background. The lens offers
superior peripheral brightness even at
the maximum aperture, and corrects for
possible flare.
The
improved DG lens design corrects for
various aberrations. This lens is
specially coated to get the best color
balance, while cutting down on ghosting
caused by reflections from the digital
image sensor. The lens provides the
utmost correction against lateral
chromatic aberration, which is a serious
problem for digital SLR cameras.
This lens
also incorporates HSM (Hyper Sonic
Motor), which ensures a quiet and
high-speed AF as well as full-time
manual focus override.
