Critical LEICA photographers looking for a universal 50mm lens offering high speed combined with optimum performance even in the close-up range will choose the F/2 SUMMICRON. Its shortest focusing distance is 28 inches and its smallest object field is approx. 11 x 5.8 inches. Its short overall length and the black light-alloy mount with a helical movement with fine thread combine to make this lens outstandingly compact, light, and easy to handle. Because of its high speed and unusually sharp definition the SUMMICRON is the most popular lens of the standard focal length.
