FAQ
Is there a dedicated filter available for the Eureka28?
To achieve the lens's ultra-compact and lightweight design, no dedicated filter is included, as doing so would increase its overall size. For users who wish to use filters, the lens features a standard E27 filter thread, allowing compatibility with third-party filters of the corresponding size.
Is there a dedicated lens hood available for the Eureka28?
The aperture ring design provides a basic level of stray-light protection. If additional shading is required, a compatible third-party lens hood can be installed.
Is the Eureka 50mm F/2 lens compatible with medium format cameras, and does it have any vignetting?
The lens can be adapted for medium format cameras. Slight vignetting occurs at aperture F/2-F/4, but it disappears when the aperture is stopped down to F/4-F/5.6.
When the Eureka 50mm lens is fully collapsed to its shortest state, will the rear structure of the lens touch the CMOS or shutter curtain?
No, when the lens is fully collapsed, the maximum distance from the lens flange to the end of the retractable barrel is approximately 0.346mm. If the distance from the camera mount flange to the CMOS/shutter curtain is greater than 0.346mm, there will be no interference.
What are the differences between the brass and aluminum versions of the Eureka 50mm lens?
1.Weight: The brass version weighs 218g, while the aluminum version weighs 120g. 2.Material: The brass version is made of chromed brass, while the aluminum version is made of aluminum alloy.
What are the collapsed and extended lengths of the Eureka 50mm lens, and what is the difference between them?
The fully collapsed length is 2.7cm, while the fully extended length is 4.12cm. The difference between the longest and shortest states is 1.42cm.
