Description — Leica 13.5cm 135mm f/4.5
The Leica 13.5cm 135mm f/4.5 Hektor is a vintage telephoto lens manufactured during the 1950s, designed for the Leica Thread Mount (LTM / M39) system. With a focal length of 135mm and a maximum aperture of f/4.5, this lens delivers the telephoto reach characteristic of mid-century optical engineering. It is compatible with M39 screw mount interchangeable lens cameras and, with adapters, can be used on a variety of modern mirrorless platforms.
Weighing 410g, the Hektor feels purposefully built — a reflection of Leica's manufacturing standards of the era. Manual focus operation puts full creative control in the photographer's hands, making it a natural choice for film shooters, rangefinder enthusiasts, and collectors who appreciate working with vintage glass. Its rangefinder classification confirms its heritage as part of the classic Leica LTM lens family, and its decades-old provenance adds genuine historical character to every shot.
