Sigma 40mm f/1.4 DG HSM Art Lens for Nikon

Crafted to meet the demanding standards of cine lenses, the Sigma 40mm f/1.4 DG HSM Art Lens for Nikon F-mount is a wide normal-length lens distinguished by its bright design and refined optical configuration. With a fast f/1.4 maximum aperture, this lens facilitates achieving shallow depth of field and selective focus effects, making it particularly versatile in various shooting scenarios, including challenging lighting conditions.

The optical design incorporates a series of low dispersion and aspherical elements, effectively controlling both spherical and chromatic aberrations to enhance sharpness and clarity. Additionally, the lens features a Super Multi-Layer Coating, minimizing flare and ghosting for improved contrast and colour accuracy, especially when shooting in strong lighting conditions. Designed to meet the exacting standards of cine lenses, the Sigma 40mm f/1.4 DG HSM Art Lens for Nikon F-mount is an exceptional choice for photographers seeking high optical performance and precision in a wide normal-length lens.

Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. The physical design features a brass bayonet mount, which offers rigidity and mounting precision along with a seal to guard against dust and moisture. Additionally, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality.

• 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.
• Short-normal prime is designed for FX-format Nikon F-mount cameras, however is also suitable for DX models where it provides a 60mm equivalent focal length.
• Impressively bright 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.
• Three F Low Dispersion (FLD) and three Special Low Dispersion (SLD) elements are featured in the optical design, and help to reduce colour fringing and chromatic aberrations for improved clarity and colour accuracy.
• One aspherical element is used to help limit distortion and spherical aberrations and also contributes to greater overall sharpness and accurate rendering.
• 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 colour-neutral imagery, even in backlit conditions.
• Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
• 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.
• Specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
• The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
• Protective coating has been applied to the front element and is both water and oil-repellent to aid in cleaning.
• This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
