Artizlab Introduces Classic-M 50mm f/1.4 Lens
Artizlab has introduced the Classic-M 50mm f/1.4, a manual-focus prime lens designed for full-frame Leica M-mount cameras. Developed in collaboration with Chinese manufacturer Funleader, the new model draws inspiration from the original Leica Summilux 50mm f/1.4 E43, reproducing several elements of its optical construction and mechanical design while introducing a shorter minimum focusing distance.
The lens follows the Artizlab Classic 35mm f/1.4, released in early 2025 and similarly inspired by an earlier Leica optical design. While the 35mm model references the Summilux 35mm f/1.4 V2, the new 50mm version is based on the E43 Summilux introduced in 1961. Both models emphasize compact dimensions, manual operation and optical rendering associated with historical rangefinder lenses rather than contemporary designs optimized primarily for maximum resolution.
The Classic-M 50mm f/1.4 incorporates seven elements arranged in five groups, matching the optical configuration of the original Summilux E43. Its diaphragm consists of 12 blades, and the 43mm filter thread also follows the historical design. According to Artizlab, the optical system has been developed to reproduce relatively soft tonal transitions, natural color rendition and gradual transitions between focused and out-of-focus areas.
Unlike modern high-resolution lenses that prioritize extensive correction of optical aberrations, the Classic-M is intended to retain some characteristics associated with older photographic optics: among them, a less pronounced rendering of fine details at wider apertures and softer transitions around highlights. However, the similarity of its optical formula to the original Leica lens does not necessarily establish identical image quality or optical performance.
The lens features an aluminum and brass construction, with a scalloped focusing ring resembling the mechanical controls of the historical Summilux. A matching hammer-tone lens hood is included, reproducing another distinctive element of the original design. The barrel measures approximately 51.8mm in length and weighs 189.3 grams, maintaining a compact profile that does not obstruct the optical rangefinder on compatible Leica M cameras.
One of the principal differences from the original Summilux concerns close focusing. While the historical E43 model has a minimum focusing distance of approximately one meter, the Artizlab lens can focus as close as 0.45 meters. However, mechanical rangefinder coupling operates only between 0.7 meters and infinity. At shorter distances, photographers must use live view or another focusing method, as the rangefinder mechanism cannot accurately indicate focus below its coupling limit.
The lens is entirely manual and does not incorporate autofocus or electronic focusing controls. Its Leica M mount allows direct installation on compatible analog and digital rangefinder cameras, while third-party adapters provide compatibility with several mirrorless systems, including Sony E, Nikon Z, Canon RF and Fujifilm X. On these cameras, focusing is performed through the electronic viewfinder or rear display.

The Artizlab Classic-M 50mm f/1.4 was initially previewed in September 2026, ahead of its planned November release. It is offered in black and silver finishes at a retail price of $399 through the Funleader online store. Both versions were listed as sold out at the time of the November 9 announcement, with further stock expected, although a specific restocking date has not been confirmed.
