Leica Elmar 105mm f/6.3 (10.5cm) - Leica L/L39/LTM Mount

The Leica Elmar 105mm f/6.3, often referred to as the 'Mountain Elmar', is a lightweight, four-element telephoto lens designed for the Leica thread mount system. Produced primarily in the 1930s, its collapsible design makes it remarkably compact for its focal length. It is noted for its high contrast and sharpness when stopped down, making it a specialist choice for landscape photography where weight is a primary concern. When inspecting a used Elmar 105mm, the condition of the internal elements is paramount, as these uncoated lenses are susceptible to haze and fungus. The collapsible barrel should lock securely into place without excessive play. We check the aperture blades for oil or corrosion and ensure the focus helical remains smooth, as original lubricants often thicken with age. The black paint or nickel finish often shows brassing on the knurled rings.
