SHOTEN TRIBUTE 01 – LTM 50mm f/1.1 for Leica M Lens Full Frame Screw Mount

The SHOTEN TRIBUTE 01 – LTM 50mm f/1.1 is the first lens in TRIBUTE, a new series from SHOTEN, Focus Workshop’s original brand. Developed in collaboration with lens creator DJ Cast Mirror, it pays tribute to the Zunow 50mm F1.1, one of the iconic ultra-fast Japanese lenses of the 1950s.

Inspired by the Zunow’s distinctive rendering, this lens reinterprets its character for modern photography. At its maximum aperture of f/1.1, it produces a soft glow, atmospheric highlights and shallow depth of field for expressive images. Stop down for a more defined look, and explore how the rendering changes with your subject, lighting and creative intent.

A supplied L39-to-M adapter ring lets you use the lens on Leica M-mount cameras. Remove the ring to use it as an L39 screw-mount lens. From its classic barrel design and engraved details to its pronounced rear-element profile, dedicated lens hood and custom packaging, every detail contributes to the character of TRIBUTE 01.

Inspired by the Zunow 50mm F1.1

The Zunow 50mm F1.1 is a notable lens in the history of Japanese ultra-fast optics. Drawing inspiration from its distinctive rendering, SHOTEN and lens creator DJ Cast Mirror have reinterpreted its character in a modern manual-focus lens.

The f/1.1 maximum aperture creates a shallow depth of field and a soft, atmospheric look wide open. It is well suited to portraits, snapshots and night scenes where you want to shape the image around available light and selective focus.

Classic design with considered details

The lens barrel combines brass and aluminum, with a classic appearance and tactile controls. The aperture ring features click stops. At the rear, the lens incorporates a pronounced profile inspired by the rear element associated with the early Zunow 50mm F1.1, sometimes nicknamed the “Ping Pong Ball.”

The lens and dedicated hood bear the TRIBUTE logo. The supplied accessories and custom red-accented box carry the same design language, making the lens distinctive both in use and as part of a collection.

Adjustable rangefinder coupling

The lens features an adjustment mechanism that lets the user fine-tune its rangefinder coupling. Depending on the camera body and individual tolerances, the focus indicated by the rangefinder may differ slightly from the best focus on the image sensor or film plane. The adjustment ring at the rear of the lens can be used to fine-tune the coupled focus position for your camera and typical shooting distances.

For detailed adjustment instructions, please refer to the product page at the Focus Workshop online store.

L39 and Leica M compatibility

With the supplied L39-to-M adapter ring attached, the lens is compatible with Leica M mount. Remove the ring to use the lens on L39 screw-mount rangefinder cameras. Compatibility and rangefinder performance may vary by camera body.
