Sigma 150mm f/2.8 EX DG OS HSM APO Macro Lens (For Canon)

Description

The Sigma 150mm f/2.8 EX DG OS HSM APO Macro Lens (For Canon) 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 polarising filters. The HSM feature provides ultra quiet high-speed autofocusing as well as full-time manual focus override. Optical image stabilisation (OS) allows you to use shutter speeds 4 stops slower than would be possible without OS.

The improved DG lens design corrects for various aberrations, using 3 Special Low Dispersion (SLD) glass elements. This macro lens is specially coated to get the best colour 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.
