Sigma 85mm f/1.4 DG HSM Art Lens (Nikon F)

The Sigma 85mm f/1.4 DG HSM Art Lens is the pinnacle of portrait photography. With a large f/1.4 aperture, you can capture stunningly shallow depth of field and smooth bokeh. Advanced technologies, including SLD and aspherical elements, ensure a clear and crisp image. The Super Multi-Layer coating also minimizes flare and ghosting. An essential for any professional photographer's tool kit.

The Sigma 85mm f/1.4 DG HSM Art Lens features a Hyper Sonic AF motor for rapid, precise focusing, along with a spacious focusing ring that allows for manual focus override for precise adjustments. A rounded 9-blade diaphragm contributes to the creation of smooth, circular bokeh. The lens is constructed with a lightweight and sturdy thermally-stable composite material and boasts a brass bayonet mount. It can also be easily adjusted and fine-tuned with Sigma's USB Dock.

• 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.
• This short telephoto 85mm f/1.4 prime lens is designed for full-frame format  cameras, and can also be used with APS-C models where it will provide a 136mm equivalent focal length.
• 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.
• Two SLD elements, one element with a high rate of anomalous partial dispersion and a high index of refraction, and one aspherical element 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.
• 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.
• 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.
• A rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality.
• The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations.
• The bayonet mount is constructed from brass for ensured accuracy and durability.
• This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
