The Sigma 40mm f/1.4 DG HSM Art Lens for Leica L-Mount is a wide normal-length lens that is characterized by a bright design & remarkable optical layout. Its f/1.4 maximum aperture helps to shoot shallow depth of field images & creates selective focus effects, while making working in difficult lighting conditions easy. Its optical design incorporates a number of low dispersion & aspherical elements, which helps improve clarity & sharpness. Its Super Multi-Layer Coating helps minimize flaring and ghosting for greater contrast and color accuracy when working in strong lighting conditions. Its Hyper Sonic Motor produces smooth, quick, and quiet autofocus performance with full-time manual focus override. The physical construction features a brass bayonet mount, which offers durability and mounting precision, & a seal to guard against moisture and dust. Its rounded nine-blade diaphragm contributes to a pleasing "bokeh" quality.
