Eureka Series
The Eureka series, inspired by the ancient Greek scholar Archimedes, celebrates a sudden discovery or enlightenment. Unlike the Simera series, which means “today” in Greek, Eureka is a new collection designed specifically for exploring vintage imagery styles.
In an era where lens designs are becoming increasingly homogeneous, the Eureka series seeks inspiration from classic lens designs of different epochs, transforming lenses into artistic vessels capable of transcending temporal boundaries and conveying genuine expression.

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.

Robust Companion Inspiration Capture
Compact in structure, the Eureka 50mm measures only 2.7cm when collapsed and extends to 4.12cm during use, making it a portable companion designed for wandering artists.
Its classic retractable design and aluminum alloy structure embody lightweight elegance and rugged reliability, operating seamlessly between-30°C to +70°C. It’s the ideal partner for capturing moments in the most extreme conditions.


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.

Optical Precision in Every Detail
This ensures exceptional optical performance, providing clarity from center to edge and pure details for analog or digital photography with stable shutter speeds.
