The Leica Summicron-M 66 f/2 is a limited edition of 660 numbered pieces that brings to life the Elcan spy lens from the Cold War. A collector's item in the M-mount that also boasts great image quality.

The Leica Summicron-M 66 f/2 is not just a lens, but a piece of photographic history. It is a modern interpretation of the late 1960s Cold War-era Elcan 66mm f/2 spy lens, originally designed for covert missions by the US Navy. Only a couple of hundred of the original models were produced and were never sold publicly. Now, the Leica Classic Line is bringing this rarity back in a strictly limited and numbered edition of 660 pieces.

Dr. Walter Mandler, the chief designer of many of Leica's classic lenses, wanted to create a lens that was as small, fast and sharp as possible. The client, the navy, had not required a specific focal length, but calculations showed that with the cutting-edge technology of the time, 66mm was the most suitable focal length for the best image quality.
In keeping with Leica tradition, the number "60" is engraved on the lens barrel. This is not a printing error, but a historical way of indicating the actual focal length, individually measured to the nearest millimetre at the factory: exactly 66.0 millimetres.
The image quality and character are exceptional. This 66mm focal length sits interestingly between the familiar 50mm normal lens and the 75mm portrait lens. It compresses the image area slightly, creating a natural perspective. At full f/2, the subject separates from the background beautifully and softly, making this a great tool for portraits or for extracting details. The 66mm focal length is therefore quite versatile, although the lens itself is far from ordinary.
This is certainly an interesting focal length for someone shooting with a Leica M body today, as crop circles are only available at 50mm and 75mm settings. But with a Leica SL camera and adapter, there is no problem.
Dimming the image creates razor-sharp resolution that can withstand huge magnifications - just like the original spy lens was supposed to. While this is clearly a collector's item, it's a full-fledged tool that demands to be used.
Mechanically, the Summicron-M 66mm F2 is pure Leica. The finish is top-notch and the feel is impeccable. In keeping with the original design, the aperture ring turns in the "wrong" direction compared to other M-series lenses. Legend has it that this was done so that the ring would turn in the same direction as the Nikon lenses used by the Navy, so that muscle memory wouldn't fail in tight situations. The front ring shows the lens' serial number, special batch number, and material number.
The original Elcan 66mm spy lens was made to order in the 1960s, with only about 200 units ever offered for public sale. It was used in covert operations by the US Navy during the Cold War. One original is known to have been on board the guided missile cruiser USS Little Rock.
The lens is an interesting piece of history brought into the modern world, and it also takes great photos.
