More Info SIGMA Art

NIKON F-mount's SIGMA 28mm f/1.4 DG HSM art lens is a versatile lens with a wide classic field of view that fits 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 multilayer 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-leaf diaphragm contributes to a pleasant quality of bokeh.

• 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 F-mount NIKON 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 focusing 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 stripes 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 multi-layered super coating has been applied to the lens elements to minimize lens reflection and ghosting and help produce contrast-rich, neutral-color images, even under backlit conditions.
• The rounded nine-leaf diaphragm contributes to a smooth and pleasant bokeh quality.
• The integrated HSM (Hyper Sonic Motor) performs 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 firing speeds.
• The bayonet mount is made of brass to ensure accuracy and durability. In addition, rubber sealing is built into the design of the bracket to make it dust and splash resistant.
• 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 characteristics of the lens and update its firmware.
