Sigma 150mm f/2.8 APO Macro EX DG HSM Lens is a super compact and lightweight large aperture telephoto lens, with life-size macro capability.
To maintain high optical performance from infinity to close-up 1:1 macro photos without accessories, this lens incorporates a "Floating Internal Focusing" (FIF) system. As a result, the lens also features a non-rotating front lens group which makes it easier to work with polarizing filters. The HSM feature provides ultra quiet high-speed autofocusing as well as full-time manual focus override.
The improved DG lens design corrects for various aberrations. This macro lens is specially coated to get the best color balance whilst cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras.
- Close focus capability of 15", with life-size magnification
- Two Special Low Dispersion (SLD) glass elements control various color aberrations and assure high image quality
- Hyper Sonic Motor HSM provides ultra quiet high-speed autofocusing as well as full-time manual focus override
