Summicron 50mm f/2, Early 2nd Generation Model
Serial number: 2,260,000 range, manufactured in 1968.

This model, which can only be found in this serial number range, features a 5-element, 6-group new design lens housed in the first-generation barrel, making it a transitional model. It has been referred to as a Transitional Model in recent years, particularly overseas. Leitz product code: 11817, the same as the later 2nd generation 6-element version. Filter size: E39.

From the Leica A-type to the M3, early Summicron and Summilux 35mm & 50mm, Noctilux f/1.2, and more recently the Apo-Summicron 50mm, Leica's early lenses have always embodied remarkable craftsmanship, design, and performance, consistently impressing enthusiasts. This early 6-element Summicron is no exception, reflecting Leitz's commitment to excellence.

It retains the refined aesthetic of the later first-generation models, and its design works beautifully with both black chrome and black paint finishes.

Moreover, this transitional model has long been praised for its exceptional rendering, and this particular lens lives up to that reputation. It delivers beautiful, sharp images and is truly an outstanding performer. A rare find.

There is slight paint wear on the filter ring edge and helicoid ring, but the lens barrel remains black and clean, maintaining a fresh appearance.

It underwent a full overhaul in March 2025. Thanks to meticulous servicing, the operation of all parts is smooth, allowing for a comfortable and enjoyable shooting experience. The rangefinder coupling is perfectly aligned, and the lens produces exceptionally sharp lines.

There is some residue near the edge of the front element that couldn't be fully cleaned during servicing, and a slight haze on the edge of the middle element, but these should not have any noticeable effect on image quality.

The lens comes with original front and rear caps, with the front cap being from a slightly later period.
