Angenieux's French rangefinder wide — the 35mm f/2.5 in Leica Thread Mount.
The Angenieux 35mm f/2.5 in Leica Thread Mount is a vintage French wide-angle from the Angenieux optical works, made in screw mount for L39 rangefinder bodies. Angenieux was a respected maker of cine and photographic optics, and its rangefinder lenses are prized among collectors of French glass.
It is a manual-focus rangefinder-coupled lens with a 35mm focal length and a maximum aperture of f/2.5. As a moderate wide it couples to the rangefinder for focusing on screw-mount and adapted bodies, with 35mm frame lines or an accessory finder used for composition.
The 35mm view is a flexible reportage and street angle, and at f/2.5 the lens gives a little more speed than typical slow wides of its era. Angenieux photographic lenses are noted for a distinctive rendering, and this one sharpens across the frame as it is stopped down.
As a scarce vintage French optic, used copies command collector interest and should be inspected carefully for haze, fungus, cleaning marks, coating wear and separation, plus focus feel and aperture oil. Confirm rangefinder coupling and infinity focus. It adapts to Leica M with an LTM-to-M ring and to mirrorless cameras via an adapter.
