First-generation Summilux 50mm f1.4, early version with reverse knurling. Serial number in the 1,660,000 range, manufactured in 1959. The Leitz product code is SOOME, later changed to 11114.
The late 1950s were a golden era for Leica, with many captivating models produced, including the Leica MP, early M2, and the first batch of M3 Black Paint. This period is often regarded as the golden age of post-war Leitz, marked by elegantly designed and beautifully finished bodies and lenses. The early Summilux is no exception, embodying a refined and dignified design.
The early version of the Summilux is known for its soft rendering at full aperture, as well as its sharp and three-dimensional depiction when stopped down. While Leitz produced many remarkable lenses, this one is truly outstanding.
The primary difference from the standard first-generation Summilux is the knurling pattern, but enthusiasts may find the early version's appearance to be more lustrous. The compatible filter is E43, and the hood is XOOIM / 12521G.
The lens comes with the original front and rear caps.
The helicoid ring and base of the lens barrel show some very fine linear scratches in places, but overall, the reverse knurling version is in quite good condition.
An overhaul was performed by the previous owner in 2023. The aperture and helicoid operate smoothly, and the rangefinder coupling is precise. You can enjoy shooting at full aperture with confidence.
There is a very faint haze-like coating deterioration around the edge of the middle element, visible only under strong LED light. This should not affect actual shooting results. The coating is fully intact, and the performance in real-world tests was very good.
