The Nano Crystal Coating System (NCS) employed in this lens is designed to enhance light transmission and minimize internal reflections, delivering superior optical performance. With an aperture range of f2.0-22, this lens features a fixed 12mm ultra-wide focal length, enabling a remarkable minimum focusing distance of just 7.9 inches.

Optimized for exceptional optical quality, this lens provides true ultra-wide 110-degree edge-to-edge coverage on APS-C sensor digital cameras. Its sophisticated optical design utilizes 3 high-precision lens elements, including 2 aspherical and 1 ED (Extra-low Dispersion) element, to ensure superior image quality across the entire frame.

Engineered for mirrorless camera systems, this lens takes a 67mm filter size and features a manual focus type, allowing for precise control and fine-tuning of the focus during image capture.

Overall, the combination of the Nano Crystal Coating System, ultra-wide focal length, and advanced optical design make this lens an excellent choice for photographers seeking to capture expansive, high-quality images with their APS-C sensor digital cameras.
