The Summilux-SL 50 f/1.4 ASPH. is designed for both speed and precision, making it highly effective in changing light conditions and fast-paced environments.

• 11 elements in 6 groups optical construction

• 2 aspherical surfaces for reduced aberrations

• High micro-contrast and edge-to-edge clarity

• Excellent low-light capability due to f/1.4 aperture

The lens maintains consistent rendering quality whether used wide open or stopped down.

Fast, Silent Autofocus System

A precision voice-coil motor ensures fast and near-silent focusing performance, well-suited for both stills and video applications.

• Smooth and accurate autofocus response

• Manual override capability

• Stable electromagnetic focus group when powered on

• Optimised for SL-series hybrid workflows

This system is designed to respond quickly while maintaining precise control in dynamic shooting conditions.

Professional Optical Design

The Summilux-SL 50 f/1.4 ASPH. is engineered for long-term professional use with robust construction and Leica-grade optical precision.

• E67 filter thread with included metal lens hood

The lens is designed to withstand intensive field use while maintaining consistent optical performance.

Balanced Design for SL Systems

Despite its high performance, the lens is engineered for balance when mounted on SL cameras, providing stable handling for both handheld photography and video.

• Approx. 584 g weight

• Approx. 75.5 mm length (without hood)

• Aluminium full-metal housing with black anodised finish
