SIGMA 28MM F1.4 DG HSM NIKON

Sigma 28mm F1.4 DG HSM Art for Nikon

The preferred wide-angle F-mount Nikon Sigma 28mm f / 1.4 DG HSM Art Lens is a versatile lens with a classic wide field of view that suits everything from street shooting to landscape photography. Impressively bright, the fast f / 1.4 maximum aperture is ideal for working in low-light conditions and also offers greater control over depth of field to isolate your subject. An advanced optical design is employed, using low dispersion glass and aspherical elements to reduce chromatic and spherical aberrations for greater clarity and sharpness. Also included is a super multi-layer coating that eliminates ghosting and flare to improve contrast and color accuracy.
In addition to its optical merits, this 28mm f / 1.4 also has a Hyper Sonic motor to produce fast, smooth, and quiet autofocus performance with full-time manual focus override. The physical design features a brass bayonet mount, offering rigidity and mounting precision along with a seal to protect against dust and moisture. Additionally, a rounded nine-blade diaphragm contributes to pleasant bokeh quality.
As 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 main wide angle is designed for FX-format F-mount Nikon cameras, however it is also suitable for use with DX models where it provides a 42mm equivalent focal length.
The incredibly 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.
Two low dispersion (FLD) F elements and three special low dispersion (SLD) elements are included in the optical design and help reduce color fringing and chromatic aberrations to improve clarity and color 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 lens flare and ghosting and help produce contrast-rich, neutral color images, even in backlight conditions.
The rounded nine-blade diaphragm contributes to a nice, smooth bokeh quality.
The built-in HSM (Hyper Sonic Motor) performs fast 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 by simply turning the focus ring at any time.
The specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting speeds.
The bayonet mount is constructed of brass to ensure precision and durability. In addition, the rubber seal is incorporated into the design of the bracket to make it resistant to dust and splashes.
A protective coating has been applied to the front element and is water and oil repellent to aid in cleaning.
This lens is compatible with the optional Sigma USB cradle to adjust different lens features and update its firmware.
