Summar 50mm f2. Serial number in the 310,000 range, manufactured in 1936. It features a hexagonal aperture and is uncoated. Leitz code is SUMUS. The aperture is marked with continental notation (f2, 2.2, 3.2, etc.). The helicoid distance scale is in feet.
This classic Leica standard lens offers rich bokeh and peripheral fall-off typical of the double Gauss design. At full aperture, it provides a soft and atmospheric rendering, while stopping down retains some softness while providing sharp detail. It is somewhat prone to flare in backlighting, so using a larger hood, such as the original SOOMP hood, can help achieve more defined images.
There are areas where the plating has worn thin, with a slight exposure of brass, reflecting the typical signs of age and use.
Fully overhauled in July 2024. The aperture and helicoid have been finely tuned for smooth operation. The rangefinder coupling is perfect.
The front element shows a number of light cleaning marks, but considering the Summar’s tendency to show wear, it is in fairly good condition. There are no signs of fogging, and the glass remains clear.
Test shots yielded excellent results. This Summar is in good practical condition and can be used well.
