Leica Summilux-M 75mm f/1.4 - Leica M-mount

The Leica Summilux-M 75mm f/1.4 is a legendary portrait lens for the M-mount rangefinder system. Designed by Dr. Walter Mandler, it is renowned for its unique rendering, characterized by a shallow depth of field and a soft, painterly bokeh at f/1.4, which sharpens significantly as the aperture is closed. It is a substantial lens for the M system, featuring a built-in telescopic lens hood in later versions. Critical checks for a used Summilux-M 75mm include the smoothness of the long-throw focus helical, which can become heavy if the lubricant has dried. SDS pays close attention to the rangefinder coupling accuracy, as this lens has a very thin plane of focus at wide apertures. We also inspect the large rear element for scratches and ensure the aperture leaves are clean and free from oil contamination.
