The 7Artisans 12mm F2.8 is an ultra-wide angle prime lens. The optical system consists of 10 elements in 8 groups and has adopted the Distagon optical design and inner rear focusing mechanism. It is currently the most compact 12mm F2.8 lens on the APS-C market.The lens is suitable for shooting landscapes, architecture, tourism, interior decorations and portraits, and practically anything else you could possibly dream up. Compared to the original model, the field of view has been largely increased. The image corner resolution and distortion control have visibly improved. The 7Artisans 12mm f/2.8 can produce even more creative shots while using a filter adapter with CPL and ND optical filters.
