 Sigma 30mm F1.4 EX DC HSM lens
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.
