Sigma 35mm f/1.2 DG DN Art (Sony) Lens - designed for Sony's full-frame E-mount mirrorless cameras, is the first fixed focal length lens from Sigma with a maximum aperture of f / 1.2. Delivering superior image quality while optimizing size and weight, the fast f / 1.2 lens helps achieve shallow depth of field as well as extremely selective focusing effects, and is also suitable for very difficult lighting conditions. Three low dispersion glass elements and three aspherical elements, including a double-sided element, effectively manage spherical aberration and distortion for enhanced sharpness and accurate rendering. In addition to imaging capabilities, the lens includes a large Hyper Sonic Motor, providing fast, smooth and quiet autofocusing with constant manual focus switching. While the aperture ring release switch can prevent unwanted noise from being recorded when shooting movies with sound, the built-in AFL button can be assigned additional functions to expand the range of operations available on the lens. In addition, the rounded 11-blade diaphragm contributes to pleasing bokeh quality. Part of the Art line of Sigma's Global Vision series, this lens is designed to achieve truly outstanding optical performance and is ideal for creative and artistic applications. It is also suitable for APS-C models with an equivalent focal length of 53mm. Weather-resistant brass bayonet construction for increased precision and rigidity. The lens is compatible with all Sony full-frame cameras available from Irbis Cinema Rental.
