FAQ
Is there a dedicated filter available for the Eureka28?
Designed with ultimate portability in mind, this lens does not come with a dedicated filter to avoid adding bulk. If needed, the lens features a standard threaded interface (E27), allowing you to pair it with filters of the corresponding specification.
Is there a dedicated lens hood for the Eureka 28?
The aperture ring structure already provides basic lens shading. If you need enhanced shading, you can install a universal lens hood.
Does the Eureka 50mm F/2 lens fit medium format cameras, and is there any vignetting?
Can be adapted for medium format cameras; there will be slight vignetting at apertures of F/2-F/4, which disappears when the aperture is stopped down to F/4-F/5.6.
When the Eureka 50mm lens is retracted, will the rearmost structure of the lens touch the CMOS sensor or the shutter curtain?
No. When the lens is retracted to its maximum state, the maximum length from the flange face to the rearmost end is approximately 0.346 mm. If the distance from the camera Mount flange face to the CMOS/shutter curtain is greater than 0.346 mm, there will be no interference.
