Tools for art. Tools as art.
Inspired by legendary lenses from the 1950s, the Eureka 28mm f/2.8 ASPH. is an exceptionally compact and high-performance pancake lens. It marks the first time exquisite lacquer artistry has been combined with brass construction, with every design detail refined over time to merge classic aesthetics with superior optical quality. Within an ultra-thin body measuring just 21.9 mm in length, it houses an optical configuration of 7 elements in 4 groups, including one DPGM high-precision aspherical element and three high-refractive-index elements. This design not only effectively corrects challenging spherical aberrations but also delivers outstanding sharpness from center to edge, making it a lens that faithfully renders scenes and reliably accompanies photographers who seek to travel light without compromising image quality.
Introducing the Thypoch "Epoch Coating" concept for the first time, this lens combines nuanced and reliable optics with retro and robust mechanics—serving as both a practical everyday lens and an inspirational piece of carry-on art. It is ideal for creators who value both aesthetics and performance.

Images are clean and vivid, crisp and detailed in focus, with smooth, natural out-of-focus areas. The 8-blade aperture creates distinctive starbursts under point light sources, adding a subtle artistic touch. Minimal ghosting and well-controlled flare ensure consistent, reliable performance even in backlit or challenging lighting conditions.

Close Perspective, Expansive Storytelling
The Eureka 28mm is an exceptionally rare M-mount lens capable of achieving a minimum focusing distance of 40 cm, undoubtedly allowing for an intimately close perspective in your photographs, the lens lets photographers get close to their subjects while the 28 mm wide-angle view captures more of the surrounding scene. The f/2.8 aperture provides a shallow depth of field up close, making the subject stand out against a softly blurred background and creating a clear sense of space. It allows for intimate moments as well as broader storytelling, giving images both narrative scope and detailed warmth.

A Flexible View for Natural Expression
The 28mm focal length inherently delivers a sense of "being on the scene". Even when you can’t step back, it captures more space, people, and stories, turning everyday scenes into rich, narrative images. Whether it’s street moments, interior scenes, or expansive cityscapes and landscapes, 28mm offers a natural, inclusive perspective that makes shooting effortless and creative. On an APS-C camera (around 42mm equivalent), it becomes a versatile, natural perspective, ideal for lifestyle photography and environmental or waist-up portraits.
