Product information "Sigma EX 30mm f/1,4 DC HSM ART"
This large aperture Sigma EX 30mm f/1,4 DC HSM lens is designed to match the APS-C size image sensors of digital SLR cameras.
The wide angle of view (102.4°at 10mm) with broader perspective, offers the photographer greater freedom of expression.
SLD and Aspherical lenses 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.
HSM Auto Focusing The HSM design provides quiet high-speed auto-focus with full-time manual focus override.
Minimum Focusing Distance and Fast Aperture The lens creates exceptionally sharp images of high contrast from its minimum focusing distance of 40cm to infinity. 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.
