Leica Summicron-M 66mm F2: Limited Run of 660, Based on Cold War Navy Lens

Leica's new Summicron-M 66 F2 is a limited run of 660 units, each serialised, drawing directly from the Elcan 66mm F2 originally built for US Navy reconnaissance in the late 1960s. The aperture ring reverses the standard M-mount turning direction, and the distance scale follows military spec. Six elements in five groups, nine-bladed aperture, 1m close-focus. Serial number 001 goes to auction.
