Classic Leitz 135mm f/4.5 telephoto in LTM — affordable vintage Leica telephoto option.
The Leitz Hektor 135mm f/4.5 in M39 thread mount is a classic Leica telephoto lens from the screw-mount era. The Hektor designation was used for Leitz's telephoto designs, and the 135mm provided useful reach for portrait and telephoto work on Leica rangefinder cameras via an accessory viewfinder for framing.
Optical quality delivers the characteristic rendering of vintage Leica telephoto designs — adequate sharpness with the lower contrast and softer overall rendering that pre-modern designs exhibit. The f/4.5 aperture is slow but was standard for telephoto lenses of this era. The lens produces images with undeniable vintage character.
Build quality is to Leitz's standards with chromed brass construction and precision mechanics. The lens includes a built-in lens hood that slides forward when deployed. The M39 thread mount provides compatibility with Leica screw-mount rangefinders and adapts to M-mount and mirrorless cameras.
On the used market, the Hektor 135mm f/4.5 is an affordable vintage Leica telephoto. For Leica screw-mount users wanting telephoto reach, and vintage lens enthusiasts exploring Leitz optics at accessible prices, it provides a genuine Leica telephoto experience without the premium pricing of rarer Leica teles.
