Leica's early screw-mount wide-angle — the 35mm f/3.5 Elmar, manual-focus rangefinder glass.
The Elmar 35mm f/3.5 is one of the earliest wide-angle lenses Leitz offered for the screw-mount Leica rangefinder system, arriving in the early 1930s alongside the 50mm Elmar. It carries the 39mm Leica Thread Mount (LTM / L39 / M39) and was engraved in centimetres as 3.5cm, marking the point where the Leica line grew beyond a single normal focal length.
This is a manual-focus, rangefinder-coupled Leica Thread Mount lens with a maximum aperture of f/3.5 at a focal length of 35mm. Construction is the brass-and-chrome or nickel of its era, and the lens screws into any L39 body. Element count, filter thread and coating vary across production runs, so verify the specifics of an individual example before relying on them.
As a 35mm on a rangefinder, it suits reportage, street and travel work where a moderate wide field and generous depth of field are useful. Early uncoated screw-mount glass of this period tends toward lower contrast and a softer, vintage rendering wide open, gaining contrast as it is stopped down.
On the used market this is collector-driven vintage glass, and values track rarity, engraving style and condition rather than raw optical performance. Check the front and rear elements for haze and cleaning marks, look for coating wear or scratches on later coated examples and any signs of element separation, and confirm the focus feel is smooth and the aperture blades are dry and free of oil. It adapts to Leica M via a 39-to-M adapter and to mirrorless with an L39 adapter.
