Sigma 24-70mm f/2.8 DG OS HSM Art Lens for Nikon F

Nikon F 24-70mm Art Zoom with Optical Stabilization

A versatile zoom for everyday shooting, the Nikon F-mount Sigma 24-70mm f/2.8 DG OS HSM Lens from Sigma covers a valuable wide-angle to portrait-length selection of focal ranges to match shooting in a variety of settings.
As part of the esteemed Art range of lenses, a sophisticated optical configuration is employed that integrates three SLD priorities and four aspherical elements to lower chromatic and spherical aberrations, as well as colour fringing, distortions, and other anomalies for increased definition and sharpness.
A Super Multi-Layer Surface treatment has additionally been applied to suppress optics flare and ghosting for accurate colour fidelity and elevated contrast, and a protective surface treatment has been applied to the front component, too, to benefit working in harsh climates.
Additionally, extending the unit's versatility, a constant f/2.8 maximum aperture affords consistent performance across the zoom range as well as increased control over separation of field.
Complementing the image-capture functions, the optics sports a Hyper Sonic Motor to produce fast, smooth, and quiet autofocus performance with continuous manual focus override.
An Optical Stabilizer additionally benefits handheld shooting by reducing the appearance of body shake for sharper imagery.
The hardware design utilizes Thermally Stable Composite surface for durability in a diverse group of settings, and a brass bayonet mount additionally provides rigidity and installation accuracy.
As part of the Art range inside Sigma's Global Vision range, this lens is developed to achieve genuinely notable optical performance and is ideally appropriate for creative and artistic uses.
Standard zoom lens is developed for FX-format Nikon F-mount cameras, however it can additionally be used with DX versions where it will deliver a 36-105mm equivalent focal-length range.
Constant f/2.8 maximum aperture is appropriate for working in provided light conditions and also supplies increased control over separation of field when using shallow depth-of-field techniques.
Three Special Low Dispersion (SLD) priorities markedly lower chromatic aberrations and colour fringing across the zoom range for improved definition and colour accuracy.
Four aspherical priorities control spherical aberrations and distortion for increased sharpness and accurate rendering.
A Super Multi-Layer Surface treatment has been applied to optics elements in order to minimize optics flare and ghosting and contribute to generating contrast-rich and color-neutral imagery, even in backlit situations.
Built-in HSM (Hyper Sonic Motor) realizes fast and quiet autofocus, which is additional complemented by an optimized AF algorithm to produce more fluid focusing performance.
The HSM additionally permits continuous manual concentrate control simply by rotating the concentrate ring at any time.
Optical Stabilizer configuration minimizes the appearance of unit shake by up to four stops to benefit making sharper imagery whenever shooting handheld.
Curved nine-blade diaphragm is constructed from hardwearing, fluorine-coated polycarbonate and additionally integrates a carbon feather cinematic for smooth performance whenever working with fast uninterrupted shooting rates.
Front lens component has been treated with a water- and oil-repellent surface treatment to benefit working in harsh environmental situations.
Constructed through a Thermally Stable Composite (TSC) surface for increased accuracy and use in wide temperature variations.
Additionally, a brass bayonet affords improved installation accuracy and stiffness. Additionally, rubber sealing is incorporated in the fitting configuration to render it dust- and splash-resistant.
Specialized electromagnetic aperture mechanism delivers increased exposure control support that is especially beneficial whenever working with fast uninterrupted shooting rates.
this optics is compatible with the optional Sigma USB Dock for fine-tuning distinct lens characteristics and updating the unit's firmware.
