APO-Telyt-M 135 f/3.4

The APO-Telyt-M 135 f/3.4 is the definitive telephoto lens for the Leica M-System. A masterpiece of optical calculation for long focal lengths. Engineered for precision over long distances, it captures subjects with razor-sharp detail and outstanding tone fidelity even at great distances. Its optical performance rivals that of studio and large-format systems – yet it’s housed in a compact, portable design that’s ready to travel.

The APO-Telyt-M 135 f/3.4 is ideal for situations where physical proximity is either impractical or intentionally avoided: on stage, in sports, in nature observation or for discreet portrait photography. Apochromatic correction enables near-total suppression of chromatic aberrations, even in scenes that are characterised by challenging contrast conditions. Its image sharpness and contrast remain consistently remarkable across the entire frame – even with an open aperture. Despite its extended focal length, the lens maintains a pleasantly compact profile and a well-balanced feel. Manual focusing is both precise and fluid, offering greater ease and control when working with shallow depth of field. An optional clip-on viewfinder for the Leica M enhances compositional precision.

Its optical design – five lenses arranged in four groups – delivers exceptional clarity and high contrast. Elements crafted from specialised glass with anomalous partial dispersion work to suppress colour fringing. Its close focus distance is 1.5 metres, which is remarkable for a 135 mm telephoto lens. The integrated, extendable lens hood provides effective protection against reflections while accentuating the lens’s streamlined silhouette. An optional tripod clamp provides stability for working safely with long exposure times. The housing is made of solid aluminium and brass. Robust, exacting and engineered for lasting performance under demanding professional conditions.
