leica 4,5 135 SR 1690448

Leica Elmar 135mm f/4.5 – M39 Screw Mount (Serial No. 1690448)

The Leica Elmar 135mm f/4.5, with serial number 1690448, was manufactured in 1959 by Ernst Leitz GmbH, Wetzlar. This is a telephoto prime lens designed for Leica’s M39 screw mount (also known as Leica Thread Mount, or LTM), and it can be used on Leica rangefinders or adapted to modern digital mirrorless systems.

Despite its compact size for a 135mm lens, it delivers classic Leica sharpness and contrast, and is particularly well-suited for portraiture, travel, and landscape photography where compression and reach are desired.
