Leica Summilux-SL 50mm f/1.4 ASPH. Lens (L-Mount)

Compact Design, Signature Leica Performance

Setting a new benchmark for creative photography and filmmaking, the Leica Summilux-SL 50mm f/1.4 ASPH. combines exceptional optical performance with a lighter, more compact design. Its bright f/1.4 maximum aperture excels in low-light situations while producing beautifully smooth, natural bokeh inspired by the renowned Summilux-M 50mm. The versatile 50mm focal length makes it an excellent choice for portraits, product and still-life photography, travel, and everyday shooting.

Distinctive Image Rendering

Designed to deliver more than technical sharpness, the Summilux-SL 50mm f/1.4 creates images with impressive depth, atmosphere, and subject separation. Shooting wide open at f/1.4 produces soft, natural background blur and a striking three-dimensional look that draws attention to the subject. As the aperture is stopped down, the lens reveals outstanding sharpness and fine detail while maintaining its signature rendering and pleasing character.

Fast, Quiet Autofocus

Built for modern hybrid workflows, the lens features a high-performance Voice Coil Motor (VCM) autofocus system that delivers fast, accurate, and nearly silent focusing. The lightweight focusing group enables rapid acceleration for responsive performance, making the lens well suited for both still photography and video production where smooth, unobtrusive autofocus is essential.

Premium Optical & Mechanical Design

Advanced optical engineering allows the lens to achieve its compact size without sacrificing image quality. Two precision-crafted aspherical elements, premium glass construction, and an 11-blade diaphragm work together to produce exceptional sharpness, smooth bokeh, and consistent performance from its close focusing distance of 1.6 feet. Optical distortion is minimized through the lens design and can be digitally corrected when needed.

Constructed with a precision-machined full-metal housing, the lens is built for professional use. An IP54-rated dust- and splash-resistant design, along with Leica's AquaDura protective coating, provides reliable performance in challenging shooting environments, making it a durable companion for everyday professional work.
