Sigma 14-24mm f/2.8 Art DG HSM Lens for Nikon F Mount

The Nikon F-mount Sigma 14-24mm f/2.8 DG HSM is an Art-series zoom lens that combines a versatile array of wide-angle focal lengths with a remarkably bright design. Its constant maximum aperture of f/2.8 is particularly advantageous for shooting in available light conditions. This lens features an advanced optical configuration that incorporates a selection of low dispersion and aspherical elements, effectively reducing both chromatic and spherical aberrations across the zoom range, thereby ensuring exceptional sharpness, clarity, and color fidelity. Furthermore, a Super Multi-Layer Coating is applied to mitigate lens flare and ghosting, resulting in imagery that is rich in contrast and true to color under various lighting scenarios.

In terms of usability, the 14-24mm lens is outfitted with a Hyper Sonic AF motor, which employs an optimized algorithm to enhance both speed and precision. It also includes a generously sized focusing ring that allows for full-time manual override, facilitating swift adjustments. The lens features a rounded 9-blade diaphragm that contributes to superior image quality by producing smooth bokeh. Constructed from a lightweight yet robust thermally-stable composite, this lens is designed for durability. Additionally, a built-in lens hood serves to protect the front element and reduce the risk of flare caused by stray light.

• As part of the Art line within Sigma's Global Vision series, this lens' is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
  
  
• Wide-angle zoom is designed for FX-format Nikon F-mount cameras, however is also suitable for DX models where it provides a 21-36mm equivalent focal length range.
  
  
• Constant f/2.8 maximum aperture is well-suited for working in available light conditions and also provides greater control over depth of field.
  
  
• Three Special Low Dispersion (SLD) elements and three F Low Dispersion (FLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy.
  
  
• Three aspherical elements control spherical aberrations and distortion for increased sharpness and accurate rendering.
  
  
• 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.
  
  
• Integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.
  
  
• Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
  
  
• Front lens element has been treated with a water- and oil-repellent coating to benefit working in harsh environmental conditions.
  
  
• Constructed using a Thermally Stable Composite (TSC) material for greater precision and use in wide temperature variations. Additionally, a brass bayonet affords improved mounting accuracy and rigidity.
  
  
• This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
