The Sigma 24-70mm F2.8 IF EX DG HSM Zoom Lens, available for Nikon and Canon DSLR Cameras, is a compact, large aperture, Standard Zoom Lens that is ideal for all general photography including portraiture and landscapes. When used on digital SLR cameras which use the APS-C (Nikon DX) sensor, this lens will provide a focal length equivalent to 36-105mm in 35mm terms.

The DG means this lens was designed specifically for digital SLR cameras and it is designed to correct for various aberrations. The lens is specially coated to achieve the best color balance, while also cutting down on ghosting caused by reflections from the digital image sensor.  Sigma 24-70mm lens features a Super Multi Layer Coating to reduce flare and ghosting. The use of ELD and SLD glass provides excellent correction of all types of aberrations. The Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function as well as full-time manual focusing capability.

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.
