Leica M3 Double Stroke Review — Precision, Permanence, Perfection.

The Leica M3 is the camera that changed how 35 mm rangefinders worked. It was the first Leica with a bayonet mount, the first with a single combined view and rangefinder, and the first that felt as if every control was designed around the photographer’s hand rather than the factory’s production line. Mine is a double-stroke version, serviced, used weekly, and it remains the most exact mechanical device I own. There are smoother cameras, lighter ones, quieter ones, but none that give the same sense of mechanical certainty.
