Brand Leica System Leica M

The Summicron-M 66 f/2 is Leica's reinterpretation of the Elcan 66mm f/2, the lens Walter Mandler designed at Ernst Leitz Canada in the late 1960s for a US Navy reconnaissance contract. Around 200 originals were built. This one starts from the same optical design, reworked to current standards at 6 elements in 5 groups. Wide open at f/2 you get soft bokeh and high contrast; stopped down it does what the original was built to do, which is hold resolution on fine detail.

Handling is deliberately odd. The aperture ring turns the opposite way from every other M lens and the meter and feet scales are reversed, both carried over from the military version, so expect a few rolls of recalibrating your hands. The lens itself is small: 60.1 mm long, 60 mm across, about 456 g, E49 filter thread, screw-on hood. The run is 660 units worldwide, numbered on the front ring. If you are weighing this against a 50 or a 75 you already own, our team can talk through how 66mm actually sits between them.

The Elcan Original

Walter Mandler designed the Elcan 66mm f/2 at Ernst Leitz Canada in the late 1960s, on a US Navy contract for covert reconnaissance work. Only around 200 were built, which makes it one of the rarest lenses in the history of the M. Many were paired with the KE-7A, the military version of the M4. The 66mm focal length was not arbitrary: it was where Mandler landed once he balanced resolution, contrast, and a body small enough to not attract attention.

Rendering At f/2

Wide open, this is a Classic Line lens: soft bokeh against high contrast, with a slightly long perspective that suits portraits. Stop it down and the original brief shows through, with resolution held on the finest detail. At 66mm you sit between a 50 and a 75, so you get a natural perspective with a little compression rather than a distinct telephoto look.

Reversed Controls

Two things will surprise you if you have shot M lenses for years. The aperture ring turns the opposite way, and the meter and feet distance scales are reversed. Both come from the military original, and both take a few rolls to unlearn. The engraving pattern follows the Elcan too, in a finer typeface, with the edition number, the optical calculation number B1047, and the internal material number on the front ring, plus a Leitz Wetzlar mark where the original said Elcan.
