7artisans 12mm F2.8 is a manual ultra wide-angle lens dedicated to cameras with APS-C matrix. The lens is extremely compact but solidly made and works well in photographing landscapes, architecture or interiors. Illuminated with a value of f/2.8 is helpful in working in poor lighting conditions. The optical design of the lens is made of 10 elements arranged in 8 groups. The lenses are covered with multi -layer coatings responsible for eliminating phenomena and lighting as well as improvement of contrast and appropriate color reproduction. The lens has an aperture made of 7 leaves and the minimum sharpening distance is only 20cm. Optionally, an adapter for 77mm filters can be used. The lens is available with canon M, Fuji X, MFT and Sony E.
