Sigma 40mm f/1.4 DG HSM Art Lens for Nikon
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 with 8K-compatible resolution and beautiful bokeh.
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. 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.
The rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality
Three F Low Dispersion (FLD) and three Special Low Dispersion (SLD) elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy
One aspherical element is used to help limit distortion and spherical aberrations and also contributes to greater overall sharpness and accurate rendering
