Vintage Leica M3 Double Stroke film camera body bundled with a Leitz Elmar 50mm f/3.5 lens.
The Leica M3 (1954–1966) was Leica's first M-bayonet camera and introduced the combined rangefinder/viewfinder window design that defines the M system to this day. The Double Stroke variant (1954–1957) features a two-stroke film advance lever and is the earliest production configuration — predating the single-stroke advance introduced in late 1957. The Leitz Elmar 50mm f/3.5 is the classic 4-element collapsible standard lens, among the earliest and most enduring designs for the 35mm Leica system.
M3 body: 35mm film rangefinder, 0.91x viewfinder magnification (highest of any production Leica M, optimised for 50/75/90/135mm framelines), M-bayonet mount, self-timer, uncoupled rewind knob, no 35mm framelines. Leitz Elmar 50mm f/3.5: 4 elements in 3 groups, f/3.5–f/16, collapsible barrel, filter thread typically 36mm (varies by generation).
The Double Stroke M3 commands a premium over later single-stroke examples due to early provenance; optically and mechanically equivalent. The M3's 0.91x finder is the sharpest and highest-magnification of any production Leica M, making it the preferred choice for 50mm shooters requiring precise focus. The Elmar f/3.5 is compact when collapsed but slower than the Summicron f/2; it is historically the pairing lens for early M3 bodies.
Test the double-stroke film advance for smooth engagement on both strokes. Check rangefinder patch brightness and horizontal/vertical alignment. Inspect the combined rangefinder/viewfinder window for haze or beam-splitter degradation. On the Elmar, test the collapsible mechanism (must lock solid in extended position), check aperture blades for oil, and verify focus coupling accuracy at close range.
