The Sigma Corporation is pleased to announce the new 30mm F1.4 EX DC
HSM for the Four Thirds fitting.
Two SLD glass elements are especially effective in the compensation of
magnification chromatic aberration.
A molded glass aspherical lens at the rear lens group reduces colour
aberration and provides high-quality image results.
The lens creates exceptionally sharp images of high contrast from its
minimum focusing distance of 40cm to infinity.
The HSM design provides quiet high-speed auto-focus with full-time
manual focus override. The large maximum aperture of F1.4 produces a
versatile lens that performs superbly in a great range of applications
including portraiture, indoor and studio work and landscape
Internal focusing means the front element does not rotate, allowing for
use of the screw-in petal shaped hood (included) and for convenient use
of circular polarizing filters. It is also possible to attach an 62mm
filter in front of the lens hood.
