Summicron-M 50 mm f/2.0, just as every good manual lens, gives us a distance scale on its body, which with little practice and combined with the rangefinder mechanism allows very precise focusing.

Leica Summicron-M 50 mm f/2.0 - Focusing


The manufacturer, for its every buyer, prepared a PDF document in which we can find thorough information about the depth of field of a given lens. So, in the case of Summicron-M 50 mm f/2.0, at the maximum aperture, setting the focus at 10 meters, we get an image sharp from about 8 meters to just over 13 meters. When we stop down to f/4.0 and don’t change the position of the manual focusing ring, the depth will rise to the range from just under 7 meters to over 19.
