Sigma 40mm f/1.4 DG HSM Art Lens for Leica L

Sigma 40mm f/1.4 DG HSM Art Lens for Leica L

This SIGMA 40mm F1.4 DG HSM Art lens for L-mount 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.

Designed within the rigorous tolerances of a cine lens, the Leica L-mount Sigma 40mm f/1.4 DG HSM Art Lens is a wide normal-length lens characterized by a bright design and sophisticated optical layout. The fast f/1.4 maximum aperture helps to achieve shallow depth of field and selective focus effects, and also suits working in difficult lighting conditions. The optical design incorporates a series of low dispersion and aspherical elements, which help to improve sharpness and clarity by controlling both spherical and chromatic aberrations. A Super Multi-Layer Coating is also featured and helps minimize flare and ghosting for excellent contrast and color accuracy when working in strong lighting conditions.

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

The rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality
