Pairing a favoured focal length with a bright maximum aperture for flexible control, the LEICA - SUMMICRON-M 35mm f/2 ASPH - Black is a standard wide-angle prime that is prized for image quality and refined optical design. Comprised of seven elements in five groups, and incorporating a single aspherical element, this lens eliminates nearly all distortions and spherical aberrations throughout the focusing range. This design also contributes to a high degree of sharpness, contrast, and clarity, and the f/2 maximum aperture enables working in difficult lighting conditions with ease. Additionally, an 11-blade aperture contributes to smooth out-of-focus rendering when working with selective focus and shallow depth of field techniques. Despite its wide-angle focal length and fast maximum aperture, this manual focus lens still remains relatively compact to benefit its use as an everyday, go-to lens for M shooters.
One aspherical element is featured in the optical design to reduce spherical aberrations and distortion for increased sharpness and clarity
