Sigma 35mm f/1.4 DG HSM Art Lens for Sigma SA and MC-11 Mount Converter/Lens Adapter for Sony E Kit

An optically advanced wide-angle prime, the Sigma SA 35mm f/1.4 DG HSM Art Lens from Sigma mixes a comfortable focal length with an especially fast design. The bright 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 layout incorporates both low dispersion and aspherical elements, which help to improve sharpness and clarity by controlling both spherical and chromatic aberrations. A floating elements system is also used to maintain performance throughout the focusing range. A Super Multi-Layer Coating is also featured, and helps to minimize flare and ghosting for greater contrast and color accuracy when working in strong lighting conditions.

Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. The physical design features a brass bayonet mount, which offers rigidity and mounting precision along with a seal to guard against dust and moisture. Additionally, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality.

The MC-11 Mount Converter enables the use of Sigma SA-mount lenses on Sony E-mount mirrorless camera bodies, and maintains full lens performance, including autofocus and auto-exposure, as well as in-camera correction technologies. An integrated LED can be used to display select Sigma lens compatibility with the adapted camera body, and the adapter also supports in-camera image stabilization. In order to maintain a high degree of image quality, the interior of the adapter is flocked to reduce reflections, and it also retains full Exif data to benefit post-production and file management.
