Introduction

The large aperture Sigma 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. Glass mold aspherical lens at rear group of lens reduces color aberration and provides high-quality image results. From 40cm minimum focusing distance to infinity, this lens creates very sharp images with high contrast. The HSM models provide quiet high-speed auto-focus shooting, as well as full-time manual focus. Large Maximum Aperture of F1.4 can perform in a great range of applications, including snapshots, portraiture, indoor shooting and landscape photography.
Sigma - HSM lenses
Sigma HSM lenses have a HyperSonic motor that enables virtually silent, highly responsive auto and manual focusing, as well as manual focus only override. The lenses are ultra compact and are supplied with a custom lens hood and feature half-stop increments on manual aperture settings, depth of field scale, distance scale, infrared correction mark. The Dual Focus functions makes it easy to hold the lens, since the focusing ring does not rotate during auto-focusing and yet provides adequate focusing torque of the focusing ring during manual focusing of the lens.
