The Sigma Art series Nikon F-mount 24-70mm f/2.8 DG OS HSM Lens is a versatile zoom lens suitable for everyday shooting in a wide range of environments. Covering a useful wide-angle to portrait-length focal length range, this lens offers flexibility in various shooting scenarios. The lens incorporates a sophisticated optical design with three Special Low Dispersion (SLD) elements and four aspherical elements, effectively reducing chromatic and spherical aberrations, color fringing, distortions, and other anomalies, resulting in enhanced clarity and sharpness. A Super Multi-Layer Coating is applied to suppress lens flare and ghosting, ensuring accurate color reproduction and high contrast. Additionally, a protective coating is applied to the front element, providing benefits when working in harsh climates. The constant f/2.8 maximum aperture ensures consistent performance throughout the zoom range and provides greater control over depth of field.
In addition to its imaging capabilities, the lens features a Hyper Sonic Motor (HSM) that delivers quick, smooth, and quiet autofocus performance, accompanied by full-time manual focus override. An Optical Stabilizer minimizes the appearance of camera shake, resulting in sharper imagery when shooting handheld. The lens’s physical design incorporates Thermally Stable Composite material for durability in diverse environments, and a brass bayonet mount offers rigidity and precise mounting.
As part of Sigma’s Art line within the Global Vision series, this lens is designed to deliver outstanding optical performance, making it ideal for creative and artistic applications. It is designed for FX-format Nikon F-mount cameras and can also be used with DX models, providing a focal length range equivalent to 36-105mm. The lens’s construction includes four aspherical elements and three SLD elements, effectively reducing chromatic aberrations and color fringing. The Super Multi-Layer Coating ensures contrast-rich and color-neutral imagery, even in challenging backlit conditions. The integrated HSM provides quick and quiet autofocus, and the optimized AF algorithm further enhances focusing performance. The lens also features an Optical Stabilizer that minimizes camera shake by up to four stops, enabling sharper handheld shots. The nine-blade diaphragm, constructed with durable, fluorine-coated polycarbonate and a carbon feather film, ensures smooth performance during fast continuous shooting. The front lens element is treated with a water- and oil-repellent coating, allowing for shooting in harsh environmental conditions. The lens’s construction, utilizing Thermally Stable Composite material and a brass bayonet mount, ensures precision, durability, and improved mounting accuracy. Rubber sealing is incorporated in the mount design, making the lens dust- and splash-resistant. Furthermore, a specialized electromagnetic aperture mechanism provides greater exposure control stability, particularly beneficial when working with fast continuous shooting rates.
For fine-tuning different lens characteristics and firmware updates, this lens is compatible with the optional Sigma USB Dock, offering enhanced customization options.
