Viltrox S 20mm T2.0 Offering a broad field of view and bright design, the S 20mm T2.0 Cine Lens from Viltrox is an ultra-wide prime lens for full-frame, Sony E-mount mirrorless cameras. The wide-angle design and fast T2.0 maximum aperture make it well suited to astrophotography use, as well as landscape, interior, and architectural shooting. Its standard 0.8 MOD cine-style gears allow you to operate the focus and iris using standard cine equipment. In its design of 12 elements in 9 groups, it incorporates a series of aspherical and low dispersion elements, which reduce spherical and chromatic aberrations for sharp, well-corrected imagery with accurate color rendering. An HD Nano multilayer coating has also been applied to suppress flare and ghosting for improved contrast when working in strong lighting conditions. The lens has a manual focus design, which permits working with subjects as close as 9.8" away, and its 14-blade iris contributes to a pleasing bokeh quality. It also features an 80mm front diameter and an 82mm filter size. Additionally, its bayonet is constructed from brass for durability and smooth operation. A lotus-style lens hood and a round lens hood that accepts filters are both included.
