DK-Optic has launched a rather beautiful new 50mm lens for Leica M-mount cameras, but rather than chasing the ultra-sharp, clinically perfect look we have come to expect from modern optics, the new Chiaro 50mm f/1.9 is looking firmly to the past. In fact, its inspiration comes from one of the most celebrated British lenses of the 1930s: the Dallmeyer Super Six 2-inch F1.9.
