Sigma announce five new lenses for Four Thirds System

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.

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 (15.75in) 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.



18-50mm F2.8 EX DC for Four Thirds Mount

F2.8 large aperture standard zoom lens designed specifically for Four Thirds system. This zoom lens is exclusively designed to ensure compact and lightweight construction as well as provides the utmost correction against lateral chromatic aberration, which is a critical problem for digital SLR cameras. This lens is specially coated to get the best color balance whilst cutting down flare and ghost caused by reflections from the digital image sensor. It has the best correction for vignetting and superior peripheral brightness is ensured.
*With Four-Thirds cameras, the angle of view will be equivalent to 36-100mm.



MACRO 105mm F2.8 EX DG for Four Thirds Mount

High contrast and excellent image quality are made possible in all shooting ranges. This macro lens maximizes the potential of Four-Thirds system. The power layout and multi layer lens coating reduce the influence of harmful light caused by reflections from the digital image sensor. A screw-in hood is included, for convenient use of circular polarizing filters.
* With Four-Thirds cameras, the angle of view will be equivalent to 210mm focal length.



APO MACRO 150mm F2.8 EX DG HSM for Four Thirds Mount

This large aperture telephoto macro lens enables you to shoot up to 1:1 life size close-up. This macro lens maximizes the potential of Four-Thirds mount system. This lens reduces the chromatic aberration of magnification, which is a critical problem for digital imaging. The best use of SLD (Special Low Dispersion) glass corrects the various color aberrations. Super multi coating reduces flare and ghost. The HSM (Hyper Sonic Motor) system provides full-time manual focus.
* With Four-Thirds cameras, the angle of view will be equivalent to 300mm.



APO 50-500mm F4-6.3 EX DG HSM for Four Thirds Mount

This versatile 10x high zoom ratio lens designed specifically for the digital imaging and it covers the wide range of the focal lengths. This lens uses SLD (Special Low Dispersion) glass for correction of color aberration, and seven-group zoom system provides a high magnification throughout the entire zoom range. Super multi coating reduces flare and ghost. The HSM (Hyper Sonic Motor) system provides quiet high-speed auto-focus shooting, as well as full-time manual focus.
* With Four-Thirds cameras, the angle of view will be equivalent to 100-1000mm.
