Sigma's
new 12-24mm F4.5-5.6 II DG HSM is an update to the 12-24mm F4.5-5.6 EX
DG ASP HSM, which has been a photographer favorite since it was first
introduced in 2002. Revisions to the lens include the inclusion of one
Special Low Dispersion (SLD) glass element and four of the company’s new "F" Low Dispersion FLD glass elements to compensate for color
aberration and provide high imagequality. FLD glass is the highest
level, low dispersion glass available with extremely high light
transmission and performance equal to fluorite glass.
The new 12-24mm
contains three glass mold elements and one hybrid aspherical lens for
advanced performance and compact and lightweight construction. It also
features Super Multi-Layer Coating to reduce flare and ghosting, and a
Hyper Sonic Motor (HSM) to ensure quiet and high-speed autofocus, while
allowing full-time manual focus override. Its minimum focusing distance
is 11 inches throughout the entire zoom range; its maximum magnification
ratio is 1:6.4.
