The NIKON F-mount SIGMA 28mm f/1.4 DG HSM Artistic Lens is a versatile lens with a classic wide field of view that suits everything from street shots to landscape photography. Impressively bright, the fast maximum aperture of f/1.4 is ideal for working in low-light conditions and also offers greater control over depth of field to isolate matter. An advanced optical design is employed, using both low-dispersion glass and aspherical elements to reduce chromatic and spherical aberrations for greater clarity and sharpness. A super multi-layer coating is also offered, which suppresses ghosting and glare to improve contrast and color accuracy.

In addition to its optical advantages, this 28mm f/1.4 also sports a Hyper Sonic motor to produce fast, smooth, and quiet autofocus focus with full-time manual focus override. The physical design features a bronze bayonet mount, which offers rigidity and mounting precision along with a seal to protect against dust and moisture. In addition, a rounded nine-blade diaphragm contributes to a pleasant bokeh quality.

• Part of the Art line within SIGMA's Global Vision series, this lens is designed to achieve truly remarkable optical performance and is ideal for creative and artistic applications.
• The wide-angle is designed for FX-format NIKON F-mount cameras, however, it is also suitable for use with DX models where it provides an equivalent focal length of 42mm.
• The impressively bright f/1.4 maximum aperture is suitable for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.
• The optical design features two F Low Dispersion (FLD) and three Special Special Dispersion (SLD) elements, which help reduce color fringing and chromatic aberrations to improve color clarity and accuracy.
• Three aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering.
• A super-multi-layer coating has been applied to the lens elements to minimize reflection and ghosting from the lens and contribute to producing rich-contrast, color-neutral images, even in backlit conditions.
• The rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
• The built-in HSM (Hyper Sonic Motor) realizes fast and quiet autofocus, which is complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also allows full-time manual focus control by simply turning the focus ring at any time.
• The specialized electromagnetic aperture mechanism provides greater exposure control stability which is especially beneficial when working with fast continuous shooting speeds.
• The bayonet mount is made of brass to ensure accuracy and durability. In addition, rubber sealing is built into the design of the stand to make it resistant to dust and splashes.
• Protective coating was applied to the front element and repels water and oil to aid in cleaning.
• This lens is compatible with the optional USB SIGMA base to adjust the different features of the lens and update its firmware.
