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.
