SIGMA APO MACRO 150mm F2.8 EX DG OS HSM for Sigma and Canon mounts scheduled to start shipping at the end of this month.
The Sigma Corporation is pleased to announce the new Sigma APO MACRO 150mm F2.8 EX DG OS HSM. This is a large aperture medium telephoto macro lens which incorporates Sigma’s proprietary Optical Stabilizer system. A floating focusing system moves two different lens groups in the optical path to different positions. This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance from infinity to 1:1 Macro. Three SLD (Special Low Dispersion) glass elements provide excellent correction of all types of aberrations and the Super Multi-Layer Coating reduces flare and ghosting. This lens has superior peripheral brightness and provides sharp and high contrast images even at the maximum apertures. Equipped with Sigma’s own proprietary OS (Optical Stabilizer) system, this lens offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible, enabling handheld close-up photography. The HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus as well as full-time manual focus capability. This lens has a rounded 9 blade diaphragm creating an attractive blur to the out of focus areas of the image. It is also possible to use this lens with Sigma’s APO TELE CONVERTERS. |
