Sigma 12-24mm f/4 DG HSM Art Lens for Nikon F

Featuring a functional variety of ultra-wide focal lengths, the Nikon F-mount Sigma 12-24mm f/4 DG HSM is a modern zoom design, distinguished by its modern design to greatly minimize distortion for achieving a high degree of sharpness. A series of low dispersion and aspherical elements reduce both chromatic and spherical aberrations all over the zoom range in order to produce high clarity and color accuracy. A Super Multi-Layer Coating is applied to suppress lens flare and ghosting for color-accurate, the contrast-rich image in a variety of lighting conditions.

Exploit handling, this 12-24mm is featured with a Hyper Sonic AF motor with an improved algorithm for speed and accuracy. The lens also gives a large focusing ring with manual override settings for quick adjustments. A rounded 9-blade diaphragm better image quality by helping to generate smooth bokeh and the lens is made up of a lightweight and long-lasting thermally-stable composite. Additionally, a built-in lens hood assists to protect the front element as well as stop stray light from causing flare.

• In the course of the Art line in Sigma’s Global Vision series, this lens’ is a plan to attain truly notable optical performance and is perfectly suited for creative and artistic applications.

• Wide-angle zoom is made for FX-format Nikon F-mount cameras, however is compatible with DX models where it produces an 18-36mm equivalent focal length range.

• Continuous f/4 maximum aperture produces constant illumination throughout the zoom range.

• A Special Low Dispersion element and five F Low Dispersion elements excellently minimize chromatic aberrations and color fringing throughout the zoom range for upgraded clarity and color accuracy.

• Three aspherical elements command spherical aberrations and distortion for improved sharpness and accurate rendering.

• A Super Multi-Layer Coating has been applied to the lens for reducing lens flare and ghosting and contributes to fabricating contrast-rich and color-neutral imagery, even in backlit conditions.

• Integrated HSM realizes fast and quiet autofocus, which is further helped by an optimized AF algorithm to create a smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.

• The rounded nine-blade diaphragm produces a smooth and pleasing bokeh quality.

• The front lens element has been served with a water- and oil-repellent coating to benefit working in difficult environmental conditions.

• Made using a Thermally Stable Composite material for increased precision and use in wide temperature variations. Additional with a brass bayonet affords upgraded mounting accuracy and rigidity. Additionally, rubber sealing is inbuilt in the mount design to render it dust- and splash-resistant.

• A specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.

• This lens is made to work with the optional Sigma USB Dock for achieving fine-tuning various lens characteristics and updating its firmware.
