Sigma five lenses for Four Thirds System
Sigma Corporation is pleased to announce the launch of five new lenses for Four Thirds System.
DC lenses: 30mm F1.4 EX DC HSM, 18-50mm F2.8 EX DC
DG lenses: MACRO 105mm F2.8 EX DG, APO MACRO 150mm F2.8 EX DG HSM
APO 50-500mm F4-6.3 EX DG HSM
Two DC lenses (18-50mm F2.8 EX DC and 30mm F1.4 EX DC HSM) and three DG lenses (MACRO 105mm F2.8 EX DG, APO MACRO 150mm F2.8 EX DG HSM and APO 50-500mm F4-6.3 EX DG HSM) are designed to maximize the potential of the digital imaging, and housed in a compact and lightweight construction. Our lens line-up for Four-Thirds mount is increased to total eight models with the introduction of these new lenses.
Large maximum aperture of F1.4, specifically designed for Four Thirds cameras.
30mm F1.4 EX DC HSM for Four Thirds Mount
This is the standard prime lens specifically designed for the digital cameras with large aperture F1.4. SLD (Special Low Dispersion) and ELD (Extraordinary Low Dispersion) glass elements are used to obtain the best possible correction for chromatic aberration of magnification, which is a critical problem for the digital imaging. From 40cm (15.75”) minimum focusing distance to infinity, this lens creates very sharp images with high contrast. The HSM (Hyper Sonic Motor) provides quiet high-speed auto-focus shooting, as well as full-time manual focus. Large maximum aperture of F1.4 can perform superbly in a great range of applications, including snapshots, portrait, and landscape photography.
* With Four-Thirds cameras, the angle of view will be equivalent to 60mm.
