The 7Artisans M50mm F1.1 lens has an optical system consisting of 7 elements in 6 groups and is based on the Sonnar formula. It includes two high refraction optical elements of index 1.9 to improve picture quality and lens portability. Our R&D process involved analysis of field curvature and image astigmatism influence on the image’s out of focus areas. Numerous corrections and improvements were made resulting in a higher quality image. Using the lens wide open at an aperture of F/1.1 delivers soft and pleasant bokeh. Stopped down to F1.4, sharpness is improved while keeping smooth out-of-focus areas. Repetitive corrections of spherical and chromatic aberration lead to precisely controlled bokeh shape, and good contrast and sharpness in the focus area of this large aperture lens.
