The 24-70mm f/2.8 IF EX DG HSM Lens from Sigma is a go-to option for many photographers thanks to a versatile zoom range from wide angle to telephoto. This model is designed for Nikon F-mount cameras and features a fast constant aperture of f/2.8 for shallow depth-of-field and enhance low-light imaging capabilities. The lens provides good image quality through the use of three aspherical elements, one ELD element, and two SLD elements to combat aberrations and distortion. Also, a Hyper Sonic Motor provides fast and quiet autofocus and the lens is designed to do all focusing internally. Additionally, the lens has a front filter thread of 82mm and a rounded 9-blade diaphragm.

This large aperture standard zoom lens covers focal lengths from 24mm and is housed in a compact construction. The latest optical design provides a compact construction and is ideal for general photography. ELD (Extraordinary Low Dispersion) glass, two SLD (Special Low Dispersion) glass elements and three aspherical lenses provide excellent correction of all types of aberrations. This lens incorporates HSM (Hyper Sonic Motor), ensuring a quiet and high speed AF as well as full time manual focus capability. This lens has a minimum focusing distance of 38cm/15in and a maximum magnification ratio of 1:5.3. The rounded 9 blades diaphragm creates an attractive blur.

ELD (Extraordinary Low Dispersion) glass, two SLD (Special Low Dispersion) glass elements, two molded glass aspherical lenses and a hybrid aspherical lens provide excellent correction for all type of aberrations. High image quality is assured throughout the entire zoom range.

The lens has a compact construction with an overall length of 94.7mm (3.7″). It is ideal for many situations such as portrait, landscape and general photography.

HSM indicates lenses equipped with a Hyper Sonic Motor, driven by ultrasonic waves. HSM ensures a quiet and high speed AF as well as full-time manual focus override by rotation of the focus ring.

The polygonal shape of a conventional iris diaphragm causes outo-focus light points to appear polygonal. A rounded diaphragm is designed to produce rounded outo-focus light points when opened to near maximum aperture. This creates attractive bokeh effects in many situations, such as when photographing a subject against an out-of-focus surface of water from which light is being reflected.

Reduced Flare and Ghosting Sigma’s own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections within the lens. All DG and DC lenses in the current Sigma range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, Sigma’s Super Multi-Layer Coating is highly effective, assuring images of outstanding contrast.
