Thypoch announces a resurgent 1950’s lens -- FF Eureka 50mm f/2

May 27, 2024

The newcomer in the field of camera lens, Thypoch announces its second series - Eureka, after Simera 35mm f/1.4 and Simera 28mm f/1.4 is becoming an on-the-slip topic for manual lens lovers. Distinct from the Simera series which highlights the modern imaging style, Eureka focuses on bringing back the historically classic lenses with contemporary engineering. The name “Eureka,” rooted in ancient Greek to express elation upon discovery, reflects Thypoch’s aspiration for users to experience similar delight with the Eureka lens.


As the inaugural lens of the Eureka Series, the Eureka 50mm f/2 is an artistic revival of a collapsible full-frame lens in the 1950s. When in use, it extends to 41.2mm, but can be collapsed to a compact 27mm, fitting easily into a pocket alongside compact cameras.




Key features:

  1. 0.9m close focus distance
  2. Classic Appearance Design in the 1950s
  3. Collapsible structure for easy pocket storage
  4. Double Gauss structure ensures edge-to-edge sharpness
  5. A fast f/2 aperture with a 12-blade diaphragm


Optics Performance

The incorporation of a 6-element, 4-group typical unsymmetrical Double-Gauss optical design within Eureka 50mm f/2 construction ensures that every shot is rendered with precision and clarity, inviting photographers to explore the boundless potential of their craft. Moreover, the inclusion of an extra-low dispersion (ED) element is able to effectively minimize chromatic aberration, and a high refractive index (HRI) element corrects curvature of field and spherical aberrations, presenting sharp, clear images even at its wide-open aperture of f/2.

Additionally, the Eureka 50mm f/2 is compatible with the 44mm x 33mm format of the Hasselblad CFV100C, ensuring exceptional image resolution of up to 100 megapixels.


With a 12-blade aperture diaphragm, Eureka 50mm f/2 guarantees circular and aesthetically pleasing bokeh, creating a dreamy and poetic atmosphere. Together with the maximum aperture f/2, users can fearlessly embrace low-light conditions, capturing every nuance of light and shadow.
