Sigma 40mm F1.4 DG HSM I Art Lens - L-Mount

Sigma SKU: 332969 | Helix SKU: SM332969

*Expected delivery Fall 2019*

The 40mm F1.4 DG HSM Art is Sigma’s first lens developed originally to live up to the sought-after angle of view and performance standard for a benchmark cine lens. This lens 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. Designed for exceptional sharpness at maximum aperture, this lens excels at available light photography. With less than 1% distortion and near non-existent sagittal coma flare, this lens demonstrates consistent optical results featuring both 8K-compatible resolution and a beautiful bokeh. The Sigma 40mm F1.4 DG HSM Art is available for Sigma, Nikon, Canon and Sony E mount camera systems.
