Description
The Sigma 20mm F2 DG DN Contemporary is a wide angle prime lens for full frame mirrorless L-mount and Sony E-mount cameras. This lens is an all metal design, with a signature I series magnetic lens cap, a manual aperture ring.
Lens construction includes three high-precision glass-molded aspherical lens elements, one SLD element, and one FLD element to suppress a range of optical aberrations and give sharper images even in the extreme corners, as well as its Super Multi-Layer Coating and Nano Porous Coating (NPC), ensures very minimal flare and ghosting.
