The 35mm f/5.6 Pancake Lens from 7Artisans is a compact full-frame lens for Leica M-mount cameras that makes carrying a camera on the go simple. The optical structure of five elements in four groups, with two ED ultra low dispersion glass elements, effectively reduces the chromatic aberration and renders virtually no color distortion. The maximum f/5.6 aperture provides a wide range of depth of field, a soft blur effect, and an exquisite circular spot with minor vignetting for a vintage look. Focus is manually adjusted, providing a close focus distance of 11.8".
