- 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.
