Description — Leica 11815
The Leica 11815 Summilux-M is a 75mm full-frame prime lens built for the Leica M rangefinder system. With a f/1.4 maximum aperture, it is capable of gathering substantial light, making it a practical choice for portrait and available-light photography. As a manual focus lens with no autofocus, it suits photographers comfortable with rangefinder focusing technique.
The 60mm filter thread provides a convenient attachment point for your preferred filters. Weighing 560g, it is a solidly built optic that adds tangible heft to any M-mount body. There is no image stabilization, so smooth results depend on good technique and taking advantage of that wide f/1.4 aperture when light is limited.
The fixed 75mm focal length places it firmly in telephoto territory, encouraging precise, deliberate framing rather than ad-hoc zooming.
