The original collapsible Leica standard lens — the Elmar 50mm f/3.5 that started it all.
The Leitz Elmar 50mm f/3.5 Collapsible is the classic Leica standard lens in LTM that retracts into the camera body for pocket-sized carry. This collapsible design defined early Leica photography, creating the compact camera system that revolutionised photojournalism and street photography in the mid-twentieth century.
Optical quality delivers the characteristic Elmar rendering — sharp centre with gentle field curvature that gives images a vintage character distinct from modern flat-field designs. The f/3.5 aperture limits low-light use but provides adequate speed for daylight photography. Coated versions offer improved contrast over uncoated originals.
Build quality is to Leitz's precision standards with chromed or nickel-plated brass construction. The collapsible barrel mechanism reduces the camera's profile dramatically when retracted, making the Leica genuinely pocketable. The L39 thread mount provides compatibility with all Leica screw-mount cameras and modern adapters.
On the used market, the Collapsible Elmar is the most commonly available vintage Leica lens. Prices vary enormously by age, condition, and coating status. For photographers wanting to experience the original Leica lens that defined 35mm photography, it provides an affordable connection to photographic history.
