Chinese manufacturer Thypoch has released the Eureka 28mm f/2.8 ASPH., a manual focus pancake lens available in Leica M-mount and Fujifilm X-mount versions. The lens was announced in November 2025 and is now shipping.

The design draws directly from the Dallmeyer Anastigmat 35mm f/3.5, the fixed lens found on the Ilford Advocate, a British camera produced in the 1950s. Ilford, still active today as a manufacturer of film and darkroom materials, no longer makes cameras, but its Advocate remains a recognizable reference point for compact analog design. The Thypoch lens reproduces several visual characteristics of that original optic, including the proportions of the barrel and, on the silver variant, a white front ring.

The optical construction consists of seven elements in four groups, including one aspherical element and three high-refractive-index elements. A multi-layer coating is also applied to the front element. Thypoch states a distortion figure of 0.462% and a minimum focusing distance of 0.4 meters, with the barrel extending slightly during close focus, adding a few millimeters to its overall length. The aperture mechanism uses eight blades.

In the M-mount version, the lens measures between 19.5 and 21.9 millimeters in length depending on focus position, and weighs 137 grams, while the X-mount variant is marginally longer. The filter thread is 27mm, and the body is constructed primarily from brass, with some aluminum alloy components.

Two finishes are offered: the matte black version uses a lacquer coating applied over brass, a  coating that wears over time, exposing the metal beneath. The pearl white version instead incorporates a fine white paint with gold powder mixed into the finish. Both are available in either mount.
