Made for Canon/Nikon cameras: 150mm f/2.8 APO MACRO EX DG HSM Lens from Sigma
The Sigma 150mm f/2.8 EX DG OS HSM APO Macro Lens (For Canon/Nikon) is a super compact and lightweight large aperture telephoto lens, with life-size (1:1) macro capability. To maintain high optical performance from infinity to close-up 1:1 macro photos without accessories, this 150mm 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, using 2 Special Low Dispersion (SLD) glass elements.
This macro lens is specially coated to get the best color balance while 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. Other features include close focus capability of 38cm and a 16.4° angle of view.
