Back to the
Original Aspiration
of the Full-frame
The liberation of photography began with an inspiration to fit a camera loaded with 35mm film into one's pocket.
In 1925, the first commercial 35mm camera was introduced, paired with the first collapsible 50mm lens, instantly ending the century-long burden of cumbersome plate cameras. Countless individuals pocketed this exquisitely compact combination and took it into the streets, warzones, and corners of the world to capture unique impressions of their epoch.
Honoring the spirit of 35mm photography, the Eureka 50mm draws inspiration from the iconic collapsible design of 1950s vintage lenses, seamlessly blending classical elegance with the resurgence of vintage aesthetics while fitting easily into a pocket alongside compact cameras.



Modern Vision with Cinematic Nostalgia
Eureka 50mm blends contemporary coating technologies with the allure of retro optical structures, creating a harmonious symphony of vintage charm and remarkable precision.
Delicately emulating the enchanting flares of vintage lenses, it reproduces the organic look through meticulous adjustments of multiple layers of coatings with varying reflectivity. It has perfectly balanced micro-contrasts and exceptionally high resolution from center to edge, offering vivid color reproduction and nuanced tonal gradations.
