Perhaps the most ingenious aspect of the Leica D is how the engineers brilliantly grafted a small-but-effective short-base, high-magnification superimposed-image rangefinder with separate viewfinder on top of the classic Leica body, creating an exquisitely compact design. The Leica D's 39mm threaded lens mount, standardized on later versions of the Leica C (or I) of '30-'31, was immortalized as the "Leica mount" used on Leicas up to the last screwmount model, the IIIg of '57-'60, all interchangeable-lens rangefinder Canons, rafts of Leica copies, and scores of enlargers. The Leica D, known as the model II in Europe, was the first Leica with a built-in coupled rangefinder, and ties for first place (with the Contax I of 1932) as the first interchangeable-lens 35mm camera to incorporate this feature, which was destined to transform the breed into the world's first true system camera.
