The Nikon F-mount 24-70mm f/2.8 DG OS HSM Lens from Sigma covers a useful wide-angle to portrait-length range of focal lengths to suit shooting in a variety of environments. A Super Multi-Layer Coating has also been applied to suppress lens flare and ghosting for accurate color fidelity and high contrast, and a protective coating has been applied to the front element, too, to benefit working in harsh climates. Additionally, extending its versatility, a constant f/2.8 maximum aperture affords consistent performance throughout the zoom range as well as greater control over the depth of field.An Optical Stabilizer also benefits handheld shooting by minimizing the appearance of camera shakes for sharper imagery. The physical design utilizes Thermally Stable Composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting precision. A standard zoom lens is designed for FX-format Nikon F-mount cameras, however, it can also be used with DX models where it will provide a 36-105mm equivalent focal length range. Three Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy. A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions Optical Stabilizer system minimizes the appearance of camera shake by up to four stops to benefit making sharper imagery when shooting handheld. The front lens element has been treated with a water- and oil-repellent coating to benefit working in harsh environmental conditions. The specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
