Light Lens Lab unveils 75mm f/1.5 Z21 portrait prime for Leica M-mount

Light Lens Lab’s new 75mm f/1.5 Z21 landed as a portrait lens with a clear point of view: give Leica M shooters a fast mid-telephoto that leans into mood, not maximum correction. The company’s pitch was not that this lens rewrote the 75mm category, but that it offered a distinct rendering signature, one built around the Z21 family’s look and aimed at photographers who want atmosphere in the frame.

That distinction matters because Light Lens Lab’s earlier 50mm f/1.5 Z21 was a recreation of the rare P. Angénieux Type S21 50mm f/1.5, a 1950s French lens that became a collector’s prize. The 75mm version moved in a different direction. Light Lens Lab described it as an independently researched and developed optical design, not a reproduction of an existing 75mm formula, and framed it as the result of continued study of what it sees as the Z21 rendering signature.

On paper, the lens stayed relatively restrained. It uses six elements in four groups and includes a lanthanide-infused element. It is manual focus, built for Leica M-mount, and measured about 71mm long with a 55mm filter thread and a 454-gram weight. Light Lens Lab said it designed, manufactured, and hand-assembled the lens in-house, and also said the image circle was expanded to improve full-frame use when the lens is adapted outside the M system.

For portrait work, the tradeoff is the point. The sample images highlighted pronounced cat’s-eye bokeh and some relatively uncorrected aberrations, which gives the Z21 a more deliberate look than the neutral, highly corrected rendering many buyers expect from modern 75mm lenses. Light Lens Lab said feedback from the earlier lens informed improvements in corner sharpness, edge performance, and sensor coverage, but this is still a lens aimed at photographers who want character first and clinical restraint second.

The price was set at $999, with preorders open and fulfillment expected to begin June 30, 2026. Light Lens Lab also offered custom front-ring engraving for an extra $110, limited to eight characters. For M-mount shooters, and for full-frame users willing to adapt it, the Z21’s appeal is not that it disappears. It is that it shows up with a very specific portrait look from the first frame.
