Optical Performance That Meets The Requirements
Of High-End Cine Lenses

This SIGMA 40mm F1.4 DG HSM Art lens for Nikon effectively arranges three FLD (“F” Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements to correct axial chromatic aberration and magnification chromatic aberration to the limit. A sharp image is formed on the focal plane with the maximum aperture and contrast with the soft bokeh in the out of focus area highlights the solidity of a subject. With a distortion of 1% or below and a sagittal coma flare corrected to the limit, it demonstrates a consistent optical characteristic over the entire sensor. This is the ultimate large-diameter standard lens that has both 8K-compatible resolution and beautiful bokeh.

Designed To Meet All Shooting Conditions

The water- and oil-repellent coating on the front lens element, together with the dust- and splash-resistant structure, ensures excellent performance even in the most challenging shooting conditions. The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures instantaneous photography movement.

Inherits The Development Philosophy

High-end cine lenses used by professional filmmakers are required to have a consistent characteristic over the entire sensor at a high level, because these lenses are used to film a subject moving freely on the screen or while panning or tilting the camera. This represents exactly the concept of the Art Line; “optical performance comes first”, and the high-end cine lenses need to be designed with this idea. The SIGMA 40mm F1.4 DG HSM | Art for Nikon is SIGMA’s first lens developed originally to live up to the sought-after angle of view and performance standard for a cine lens. This new perspective to ensure the quality of professional equipment for visual production empowers it to breakthrough also as an interchangeable photographic lens.

Nikon Electromagnetic Diaphragm Mechanism Included

This SIGMA 40mm F1.4 DG HSM | Art for Nikon includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the compatible camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting.
