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

Pairing a versatile range of wide-angle focal lengths with an impressively bright design, the Nikon F-mount Sigma 14-24mm f/2.8 DG HSM is an Art-series zoom, distinguished by its fast f/2.8 constant maximum aperture to suit working in available lighting conditions. Featuring a sophisticated optical design, this lens utilizes a series of low dispersion and aspherical elements to minimize both chromatic and spherical aberrations throughout the zoom range in order to achieve high sharpness, clarity, and color accuracy. A Super Multi-Layer Coating also helps to suppress lens flare and ghosting for color-accurate, contrast-rich imagery in a variety of lighting conditions.

Benefitting handling, this 14-24mm is equipped with a Hyper Sonic AF motor with an optimized algorithm for speed and accuracy. The lens also offers a large focusing ring with full-time manual override settings for quickly making adjustments. A rounded 9-blade diaphragm improves image quality by helping create smooth bokeh, and the lens is constructed from a lightweight and durable thermally-stable composite. Additionally, a built-in lens hood helps to protect the front element as well as prevent stray light from causing flare.

• 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 St
