The Sigma Corporation is pleased to announce the launch of the new 30mm F1.4 EX DC HSM lens.
This large aperture 30mm F1.4 EX DC HSM lens is designed to match the APS-C size image sensors of digital SLR cameras. 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 photography.
