Apo-Telyt-M 135mm f3.4. The longest focal length Leica M lens with rangefinder coupling. Leica product code 11889. Serial number in the 3.87 million range, manufactured in 1999. Made in Germany.
Despite its simple 4-group 5-element design, it is an apochromatic lens that delivers sharp results even at full aperture. The minimum focusing distance is 1.5 m. With its built-in hood, it remains compact despite being a telephoto lens.
Filter size is E49.

No signs of use, with a very beautiful appearance. Truly in like-new condition.
All functions operate normally, and the handling is smooth. There is a very slight tendency toward back focus overall, so for precise focusing, shooting with live view is recommended.
The glass is clear without haze or cleaning marks, providing its original image quality.
Comes with genuine front and rear caps.
