The 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, the Sigma 150mm f/2.8 EX DG HSM 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.

Note: This lens (similar to Nikon "G" type lenses) does not have an aperture ring on the lens, and is not fully compatible with the F4, N90-series, N70, N8008-series and N6006 (or older model) cameras. With these cameras, only programmed auto or shutter-priority auto exposure mode can be used.
Note: HSM lenses, while able to manually focus with all Nikon F-mount cameras, will not autofocus with certain older film AF cameras. This is the same limitation as with Nikon's own AF-S lenses. Incompatible models are: N60, N55, N8008/s, N6006, N5005, N4004 & N2020.
