Sigma 18-35mm f/1.8 DC HSM Art Lens for Nikon F

Famous for its unique fast and versatile design, the Nikon F Sigma 18-35mm f/1.8 DC HSM is featured with artistic zoom, covering wide-angle to normal focal lengths. Distinguishing itself from the pack, this zoom includes an extraordinary bright f/1.8 constant maximum aperture, which is compatible in difficult lighting conditions and gives you the impressive depth of field control throughout the zoom range. The optical design incorporates a series of SLD and aspherical elements, which help to produce high clarity and sharpness by suppressing various aberrations, color fringing, and distortion. A Super Multi-Layer Coating has also been applied, to the lens, which controls lens flare and ghosting for improved contrast and color accuracy. Balancing the optical merits, this 18-35mm also supports an advanced Hyper Sonic Motor, along with an internal focusing design, to promote fast, quiet, and precise autofocus performance.

• As a part of the Art line within Sigma’s Global Vision series, this lens is designed to produce truly notable optical performance and is ideal for creative and artistic applications.

• Wide-to-normal zoom is compatible with DX-format Nikon F-mount cameras and provides a 27-52.5mm equivalent focal length range.

• Impressively bright constant f/1.8 maximum aperture is made for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.

• Five Special Low Dispersion (SLD) elements are featured in the optical design and help to minimize the color fringing and chromatic aberrations for achieving improved clarity and color accuracy.

• Four aspherical elements are used to help reduce distortion and spherical aberrations and also contribute to achieving greater overall sharpness and accurate rendering.

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

• Integrated HSM, along with an internal focusing system, produces quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also allows full-time manual focus control simply by rotating the focus ring at any time.

• Rounded nine-blade diaphragm feature for a smooth and pleasing bokeh quality.

• Constructed using a Thermally Stable Composite material for greater precision and use in every temperature variation. 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.
