Leica's compact collapsible fifty — the Elmar-M 50mm f/2.8 that retracts into the body.
The Leica Elmar-M 50mm f/2.8 is a collapsible standard lens for the Leica M system. Its defining feature is the ability to retract into the camera body when not in use, creating an ultra-compact storage profile. The Elmar designation indicates a simpler, more affordable optical design than the Summicron or Summilux alternatives. It provides classic 50mm coverage at a modest aperture.
Optical performance is good. Sharpness is very good from f/2.8 — the modest aperture means the lens is always near its performance peak. The Elmar design is straightforward but well-executed. Colour rendition has the Leica signature — neutral, precise, and with the micro-contrast that defines M-mount lenses. The f/2.8 limits shallow DOF work.
Leica M mount with rangefinder coupling and collapsible barrel. Filter thread is 39mm (E39). Weight is approximately 175 grams — one of the lightest M-mount fifties. Build quality is excellent with Leica engineering. The collapsible mechanism allows the lens to retract for compact storage — a unique feature that makes the camera pocketable with some M bodies.
Available on the used market at moderate Leica prices. Check the collapsible mechanism for smooth operation — ensure it locks securely in both extended and retracted positions. The retractable design makes this uniquely compact for a Leica fifty. Best for photographers who value portability above aperture speed.
