The Light Lens Lab M 75mm f/1.5 Z21 is a fast medium-telephoto manual focus lens for Leica M-mount rangefinder cameras. As part of the Z21 series, it carries forward the classic rendering concept inspired by the legendary Angenieux 50mm F1.5 Type S21, reinterpreted with modern optical glass, updated coating technology, and a 75mm design optimized for portraits, detail work, and expressive subject separation.
With its bright f/1.5 aperture and 75mm perspective, this lens delivers smooth background blur, gentle tonal transitions, and a natural three-dimensional look. It is designed for photographers who want a classic character lens rather than a clinically modern optic, while still benefiting from improved edge performance and better overall image consistency.
The matte black barrel gives the lens a refined, understated appearance. Precision-machined focusing and aperture rings provide a tactile manual shooting experience, matching the feel expected by Leica M users and rangefinder photographers.
