Leica Summilux-M 50mm f/1.4 - Leica M Mount

The Leica Summilux-M 50mm f/1.4 (Pre-ASPH) is a legendary fast standard lens, known for its characteristic rendering and compact size. Versions of this lens spanned several decades, with the later E46 version being highly sought after for its improved close-focus distance and built-in hood. It offers a soft, romantic quality at f/1.4 which sharpens considerably by f/2.8, making it a versatile tool for both artistic and clinical photography. Prospective buyers should check for focus accuracy, particularly on wide-aperture rangefinder lenses where tolerances are slim. The focus throw on older versions can be quite long; ensure it moves smoothly without dry spots. SDS checks the internal glass for haze or fungal growth, common in older optics. We also verify the condition of the aperture ring clicks and ensure the diaphragm is free from oil, which can cause slow operation on film M cameras.
