Summilux-R 50mm f1.4, later version with built-in hood. Three-cam type. Leitz product code 11875. Serial number in the 3.23 million range, manufactured in 1982, made in Germany.
The Summilux-R 50mm was introduced in 1969 for the Leicaflex SL. The early version had a detachable hood, while this later version features an integrated hood. Optical construction consists of 7 elements in 6 groups, modified Gauss design. Minimum focusing distance is 0.5 m. Filter size E55.
This lens is known for its dreamy rendering, combining a highly resolved focal plane even at full aperture with a beautifully smooth, melting bokeh. It performs wonderfully even on today’s ultra-high-resolution digital mirrorless cameras.

There is slight paint loss on the aperture ring and surrounding parts, but overall it remains in good cosmetic condition.
Fully overhauled in September 2025. Both the aperture and helicoid operate very smoothly, providing a pleasant handling feel.
A thin scratch resembling a fiber can be seen on the rear element, but it has virtually no effect on actual images. No haze is present. A highly practical lens.
Comes with genuine front and rear caps, and a third-party UV filter.
