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

The Leica Summilux-R 50mm f/1.4 is a classic standard prime for the Leica R-series SLR system. Known for its 'Leica glow' at wider apertures and excellent sharpness when stopped down, it is a favourite for portrait and low-light photography. Several versions exist, with later models featuring a larger 60mm filter thread (E60) and improved optical performance. The lens is frequently adapted for use on modern mirrorless systems due to its tactile handling and distinct rendering. For used R-mount lenses, the focus helicoid should be checked for smoothness, as the grease can thicken over time. Inspect the built-in lens hood for any rattling or looseness. SDS meticulously checks for internal haze and 'balsam separation' in the rear elements, which can occur in older vintage glass. We also verify that the aperture blades are snappy and free from oil, ensuring the diaphragm closes instantly when the shutter is tripped on a native R-body.
