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.
The Eureka series stands out as a vintage camera lens in today's standardized optics world. Drawing inspiration from classic designs across different eras, it transforms your photography into timeless artistic expression.

EUREKA
50mm f/2 full frame. Homage to the Past

Back to the Original Aspirationof 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.
The Eureka 50mm honors the spirit of 35mm photography with its iconic collapsible design inspired by 1950s vintage camera lenses. This compact lens blends analog charm with contemporary optical performance, perfect for street photography and everyday carry.
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.



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.
Through carefully engineered multi-layer coatings, this vintage photo lens recreates the enchanting flares and organic look of classic optics while delivering exceptional edge-to-edge sharpness, vivid colors, and rich tonal gradations.

Luminous Reverie Dreamlike Immersion
Fearlessly embrace low-light environments with the maximum f/2 aperture of the Eureka 50mm lens. Its shallow depth of field paints delicate and soft bokeh, seamlessly transitioning between in-focus and out-of-focus areas.
With a 12-blade aperture diaphragm, the lens guarantees circular and aesthetically pleasing bokeh, creating a dreamy and poetic atmosphere.

Cute little lens takes amazing photos. It looks cool and feels cool. Only thing a little inconvenient is the UV OR hood is easily to pull off when pulling the lens out. If it can be stronger attached to lens will be excellent

Still have to try it! But it’ll be soon. UPDATE: As promised, here are a couple of pics.
Farhiz K. 5/5 Verified
This lens is like the Tardis - so much fun packed in a tiny retro package. The tab focusing is a delight to use. I can zone-focus by feel, it is so fast.
Derby C. 5/5 Verified
It’s a very nice and compact lens. The bokeh is beautiful and distinctive, and the sharpness is good. Extending and retracting the lens is not always completely smooth, and it’s also quite disappointing that the aperture ring is not click-stopped. As a result, you sometimes accidentally change the aperture while focusing, which is very inconvenient.It’s also a shame that standard filters cannot be mounted on the lens. On the other hand, a UV filter is included, which is a nice bonus.Focusing is smooth, and although I was initially concerned about the infinity lock, it works perfectly fine. That said, I personally wouldn’t have minded if it had been left off altogether.
Geert K. 3/5 Verified
I like the look and style of that lens, it makes a lot of fun to take photos with this lens and additional it looks very stylish on my Leica M EV1.
Peter Gierl P. 5/5 Verified
Great lens for the price. It‘s light and surprisingly sharp, even wide open. The option to collapse the lens is great. I only wished it had a clickable aperture ring then it would be perfect.
Markus K. 5/5 Verified
It’s a beautifully designed lens with a certain vintage charm, especially when you use it with cameras that bring this retro design back to life. It makes you feel closer to classic photography. The bokeh could be more distinctive.
Thorsten N. 3/5 Verified
The manual is not thorough I had difficulties operating the lens at first. It would not take images. However, after so much setting searching I managed to operate. The manual does not detail operating steps. Also no enough videos are available online nor on the website
Lamees A. 4/5 Verified
I had been looking for a pancake lens to pair with my ZF and the Eureka 28mm compliments well the retro design of the camera. It performs really well and the light nibble I flaw is the really strong vignetting (it's minor because easily fixed in post).
Seif A. 5/5 Verified
Tack sharp from wide open! Only one dissatisfied point is… actual pan-focusing zone seems to be… a little bit narrower than the lens markers. Others will be good.
Yoshiki I. 5/5 Verified
Delivery got delayed, but.... the lens is a beauty !! I just love the way it looks so premium !! Didn't use it a lot yet, the initial photos looked amazing - I couldn't be happier
Edson Luis D. 5/5 Verified
The focus tab is very easy and fast way to focus. Once you master how to focus images are sharp. I like the small size of the lens, too. Perhaps only complaint is the lens cap. Since it doesn't screw or clip it could easily fall off and lose. Aperture ring is small by design. No real complaint there. Version 2 could have clicked apertures, tho. Overall I find the lens a joy to take photos with.

Tinny but mighty - its a gem!

Arrived quickly with no issues. Nicely packaged and the lens is very well made. I haven’t made any images yet but looking forward to it.
Richard H. 5/5 Verified
The wait was totally worth it. This lens is incredibly compact—it’s almost like a body cap when mounted on the camera. Carrying it around all day for street photography is effortless, making it perfect for travel and daily documentation. Compared to my previous 28mm lens, this one is lighter and more convenient.
Henry H. 5/5
Despite its small size, it has a decent minimum focusing distance, allowing you to shoot close-up details like coffee and small street objects. Its shooting flexibility exceeds my expectations.

If it had threads for filters and a hood it would have been perfect.

The lens is everything I hoped it would be and it looks great adapted my Sony rangefinder style cameras. Don't ever change the focus lock like you have with the Simera models. I probably would have bought one of those as well if you still had the original design available. Don't ever take it off this one.
