Rare Lens Developed for the U.S. Navy Reborn as a New Product... Leica Unveils the 'Summicron-M 1:2/66'

[Financial News] Leica Camera announced on the 4th that it will introduce the Leica Summicron-M 1:2/66, a new product that reinterprets the rare ELCAN 66mm f/2 lens developed for the United States Navy (USN) in the 1960s. The Leica Summicron-M 1:2/66 is distinguished by adding a unique 66mm focal length to Leica's classic lens lineup.
The original ELCAN 66mm f/2 was developed in the late 1960s by Walter Mandler, then head of development at Ernst Leitz Canada, at the request of the USN. Designed for covert reconnaissance photography, the lens retained an appearance similar to that of a conventional lens while being engineered to deliver high resolution and delicate contrast.
To achieve both a compact size and strong optical performance, it adopted the unusual 66mm focal length rather than the more common 50mm or 90mm options. With only approximately 200 units produced, it is regarded as one of the rarest lenses in the Leica M system to this day.
The Leica Summicron-M 1:2/66 is based on the original ELCAN's optical design but has been optimized to meet modern standards. At its maximum aperture of f/2, it delivers smooth bokeh and high contrast. As the aperture is stopped down, it is designed to render even fine details sharply.
The 66mm focal length sits between a classic 50mm lens and a longer focal-length portrait lens. Leica explained that it provides a natural perspective and can be used in a variety of shooting situations, including portrait photography.
The original ELCAN's operating method has also been carried over. The aperture ring rotates in the opposite direction from that of conventional M lenses, while the distance scale is based on military specifications from the period.
The design also incorporates features of the original model. Limited to 660 units worldwide, the new product bears engravings reminiscent of the original ELCAN. The front ring is engraved with each product's serial number, the optical design number 'B1047,' and a 12-digit internal part number. Instead of 'ELCAN,' it bears the name 'Leitz Wetzlar.'
The small number '60' engraved on the side of the lens is another detail reflecting the original. It refers to the actual measured focal length of 66.0mm and recreates the marking system used on precision lenses at the time.
A Leica Camera representative said, "The Leica Summicron-M 1:2/66 is meaningful because it continues today the story of a special lens rooted in Leica's history." The representative added, "With its unique 66mm focal length, it will add a new option to the classic lineup."
