Description — Zeiss 18mm f/4
The Zeiss 18mm f/4 Distagon T* ZM is a wide-angle prime lens built around the Leica M mount, engineered to deliver full-frame coverage for rangefinder photographers. With a fixed 18mm focal length, it offers a broad perspective well suited to subjects where expansive field coverage matters. The f/4 maximum aperture keeps the optical design compact and the lens lightweight at just 350g, making it a practical companion on extended shoots.
Focusing is entirely manual, consistent with the deliberate, hands-on approach that defines rangefinder photography. There is no image stabilization, so shutter speed discipline is important when shooting handheld. The 58mm filter thread provides easy access to a wide selection of standard filters for contrast control or light management.
As a dedicated prime lens within the rangefinder camera system, this Zeiss ZM is designed for photographers who value a fixed focal length and full manual control over their wide-angle work.
