Description — Leica 35mm f/1.4 ASPH
The Leica Summilux-M 35mm f/1.4 ASPH is a prime, manual-focus lens built natively for the Leica M mount. Covering full-frame sensors, it delivers a 35mm wide-angle perspective with a fast maximum aperture of f/1.4, giving photographers the ability to work in lower light conditions while maintaining control over depth of field. Weighing just 320g, the lens is well-suited to the compact, deliberate nature of rangefinder photography.
A 46mm filter thread allows straightforward use of standard screw-in filters for creative and practical applications. The lens operates entirely without autofocus or image stabilization — both confirmed absent in the specifications — placing full creative control in the hands of the photographer. Designed for Leica's mirrorless M-system, it integrates directly with compatible M-mount bodies without the need for adapters.
As a wide-angle prime, it encourages a purposeful approach to composition, with no zoom range to rely on.
