Description — Leica 11115
The Leica 11115 is a 35mm prime lens built around the Leica R mount, designed to cover a full-frame sensor or film plane. It offers a maximum aperture of f/2, making it a reasonably fast standard prime well-suited to a range of photographic applications. Focusing is entirely manual, placing full control in the photographer's hands with no autofocus system involved.
The lens weighs 475g and features a 55mm filter thread, offering broad compatibility with standard filter accessories. With no image stabilization, users should be mindful of shutter speed when shooting handheld in lower light. As a Leica R mount lens, it is natively compatible with Leica R-series bodies and can be adapted to other systems using widely available third-party mount adapters.
Its prime construction at 35mm offers a fixed perspective in the standard focal length range, encouraging a purposeful approach to framing and composition.
