Truly wide and truly fast, the Sigma 20mm f/1.4 DG HSM Art Lens for Nikon is a member of the venerable Art series of Global Vision lenses from Sigma and pairs a sophisticated optical design with a robust physical construction. Comprised of 15 elements in 11 groups, the lens design includes two “F” Low Dispersion (FLD) elements, five Special Low Dispersion (SLD) elements, and two aspherical elements to significantly reduce chromatic and spherical aberrations, as well as limit distortion for clean, sharp, and evenly illuminated imagery. A Super Multi-Layer Coating has also been applied to minimize surface reflections, flare, and ghosting for increased contrast and color accuracy. The wide focal length and consistent image quality make this lens especially suitable for landscape, interior, architectural, and astrophotography applications, while the fast f/1.4 maximum aperture deems it ideal for natural and low-light shooting.
Complementing the optical performance is an equally adept Hyper Sonic Motor, which provides fast, smooth, and near-silent autofocus performance. This focusing motor also enables full-time manual focus override at any time just by rotating the focus ring for refined manual control and focusing as close as 27.6cm. The lens barrel is constructed using a Thermally Stable Composite material, which supports working in a wide variety of temperatures and conditions, and the lens mount is constructed from brass for long-term durability and mounting accuracy.
Additionally, this lens is also compatible with the optional Sigma USB Dock for fine-tuned control over focusing parameters and other lens characteristics.
Key Features of the Sigma 20mm f/1.4 DG HSM Art Lens for Nikon
- F Mount Lens/FX Format
- Aperture Range: f/1.4 to f/16
- Two FLD Elements and Five SLD Elements
- Two Aspherical Elements
Two FLD, five SLD, and two aspherical elements
Two FLD, five SLD, and two aspherical elements have been incorporated within the lens design to correct for chromatic aberrations throughout the entire focusing range and help to ensure high image sharpness, clarity, and contrast regardless of focus point or aperture setting. This optical design also helps to control distortion and limit vignetting.
Integrated HSM (Hyper Sonic Motor)
The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.
Super Multi-Layer Coating
A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
Part of the Art line within Sigma’s Global Vision series
As part of the Art line within Sigma’s Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
Fast f/1.4 maximum aperture
Fast f/1.4 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.
Prime wide-angle 20mm f/1.4 lens
Prime wide-angle 20mm f/1.4 lens is designed for FX-format Nikon F mount DSLRs, and can also be used with DX models where it will provide a 30mm equivalent focal length.
Constructed using a Thermally Stable Composite (TSC) material
The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations.
Fixed petal-shaped lens hood
A fixed petal-shaped lens hood helps to reduce lens flare when working in strong lighting conditions and also offers some protection to the front element of the lens.
Compatible with the optional Sigma USB Dock
This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
Bayonet mount
The bayonet mount is constructed from brass for ensured accuracy and durability.
Rounded nine-blade diaphragm
A rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality.
