Leica 50mm f/2.8 Elmar Leitz Wetzlar Collapsible M-Mount Lens, Germany, Chrome {E39} 11612

Leica's collapsible 50mm Elmar: German optics, pocketable form.

The 50mm f/2.8 Elmar with collapsible barrel is one of Leica's most enduring lens designs, manufactured by Ernst Leitz GmbH in Wetzlar, Germany. The collapsible barrel is the defining feature here: push it into the body and the whole package shrinks to a size that slips into a coat pocket, then extend and lock it into position before shooting. For anyone traveling light with a M-body, this changes the equation entirely compared to a fixed-barrel 50mm.

At f/2.8 maximum aperture, the Elmar sits in a well-established optical tradition that prioritizes drawing character and compactness over maximum light gathering. The E39 filter thread accepts a small range of filters and lens accessories scaled to match the lens's proportions. The chrome finish, period-correct for classic Leica M bodies, holds up as a natural pairing to chrome M2, M3, and M4 bodies.

This is a lens with a specific logic to it. Shooters who want the most compact possible M-mount 50mm, paired with optics built to exacting German standards, will find the 11612 Elmar earns its place on the camera than sitting in a bag.

Who It's For

Street photographers who carry a M-body all day will appreciate the collapsed profile, which reduces the kit to near-jacket-pocket size without swapping to a wide angle. Travel photographers pairing this with a chrome M3 or M4 get a period-matched, historically coherent setup that also shoots. Film shooters working in bright daylight find f/2.8 plenty of aperture for sunny-16 exposures. Collectors and shooters bridging both worlds will recognize the Ernst Leitz Wetzlar provenance as a mark of specific manufacturing lineage within the broader Leica M lens canon.

FAQ

How much does the lens shrink when collapsed?

The barrel retracts fully into the lens body for pocket-sized portability, though exact dimensions vary by serial range and production era.

Is this a single-coated or multi-coated lens?

Leica produced both versions across different manufacturing periods; check the serial number and any markings on the barrel to confirm your specific unit's coating generation.

Can you use modern filters on the E39 thread?

Yes, E39 is a standard size with wide filter availability, though you may need step-up rings if you want to use larger filters from other lenses.

Will this Elmar work on digital M bodies like the M9 or M10?

The Leica M bayonet mount is compatible across all M bodies, digital and film, but digital bodies will meter and autofocus differently than film bodies designed for this lens era.

How does the f/2.8 aperture compare to faster 50mm M-mount options?

The Elmar trades maximum light-gathering for compact size and optical simplicity; if you need f/2 or faster, the Summicron or Summilux 50mm offer wider apertures but in fixed barrels.

What's the optical formula? How many elements?

Classic Elmar designs typically use 4 elements in 3 groups, though specific optical specs can shift between production batches and decades.
