Sigma 14mm f/1.8 DG HSM Art Lens for Nikon F

Featured for fast and wide actions, the Nikon F-mount 14mm f/1.8 DG HSM from Sigma is a special wide-angle prime lens made to achieve a high-resolution, well-corrected image. As part of the Art line of lenses, this lens is featured with a focus on image quality and rendering and utilizes both FLD and SLD glass elements to command chromatic aberrations and color fringing for notable clarity. Four aspherical elements, counting with the front large-diameter precision-molded glass element, also help to minimize distortion and spherical aberrations for great sharpness and accuracy. Additionally, a Super Multi-Layer Coating has been put into individual elements to decrease lens flare and ghosting for improved contrast while working in strong lighting. Perfectly made for astrophotography and low-light outdoor shooting, this lens presents a unique blend of a broad perspective and fast, flexible performance.

Applauding the optical performance is an equally adept Hyper Sonic Motor, which produces quick, smooth, and silent autofocus performance. This focusing motor also permits manual focus override at any time by just rotating the focus ring for clear manual control and zooming as close as 10.6″. The lens barrel is made using a Thermally Stable Composite material, which helps to work in several of temperatures and conditions, and the lens mount is made from brass for long-term durability and mounting precisely. Additionally, this lens can be used with the optional Sigma USB Dock for fine-tuned control over focusing parameters and other lens characteristics.

• As a member of the Art line in Sigma’s Global Vision series, this lens is made to produce truly notable optical performance and is perfectly suited for creative and artistic applications.

• A prime wide-angle lens is constructed for FX-format Nikon F-mount DSLRs, however, it is compatible with DX models where it will produce a 21mm equivalent focal length.

• Bright f/1.8 maximum aperture is made for working in low and harsh lighting conditions.

• Three F Low Dispersion and four Special Low Dispersion elements are inbuilt within the optical design and help to minimize color fringing and chromatic aberrations for upgraded clarity and color accuracy.

• Four aspherical elements, including one large, 80mm-diameter precision-molded glass aspherical element, help to reduce distortion and spherical aberrations for upgraded sharpness.

• A Super Multi-Layer Coating has been coated to lens elements in order to reduce lens flare and ghosting and help to achieve contrast-rich and color-neutral image, even in backlit conditions.

• The integrated HSM realizes fast and smoothes autofocusing, which is further accompanied by an optimized AF algorithm to produce smoother focusing performance. The HSM also allows manual focus control simply by rotating the focus ring at any time.

• Specialized electromagnetic aperture mechanism helps in producing greater exposure control stability that is especially helpful while working with fast continuous shooting rates.

• The lens is made using a Thermally Stable Composite (TSC) material, along with traditional metals, for achieving greater precision and could be used in wide temperature variations.

• The bayonet mount is made from brass for guaranteed accuracy and durability. Additionally, rubber sealing is included in the mount design to render it dust- and splash-resistant.

• This lens can be used with the optional Sigma USB Dock for fine-tuning various lens characteristics and updating its firmware.
