Homage to the Past

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.

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.

Featuring a 6-element, 4-group typical double-gauss optical design, the Eureka 50mm incorporates cutting-edge optics. An extra-low dispersion (ED) element effectively minimizes chromatic aberration, while a high refractive index (HRI) element corrects curvature of field and spherical aberrations.
