Here's the link to printables for lensboards and db shutter adapter. https://www.printables.com/model/578...d-for-hypergon

Finally, the lens is ready.
Elevan Film(https://elevanfilm.com/product/hypergon75/) is the sales agent now. Due to some transaction fee, the final price is USD 539 + p&p.
It's not a volume product so sometime it take a while to ship.

The filter mount is redesigned with ball bearing. And I found a manufactruer of silicon mask for these perfect aperature.
And the next phase is PVT. So we will see the final product very soon.
It seems the attachment amount has match the limit. Maybe a new thread is needed? I put these updates onto youtube

The final color will be shiny black(raw surface in the last post) with shiny brass parts. As for the patent and markings, the Hypergon patent is expired but the C.P.GOERZ is still owned by OPC in germany. I've asked a lawyer, it's not protected in any other countries. But it is still a hitorical trademark so I'm not sure if it is fine to use it on this lens. Maybe IMO GOERZ (In memory of GOERZ) would be better since GOERZ alone is not an trademark.
Another news is for camera. We are going to launch the cheapest 8x10 camera system ECO810. It is an metal light weight modular camera system that is even cheaper than intrepid. We've sold dozens of it in Asia and currently tring to sell it to North Amercia and Europe. There will be another post about it.
Update 2023-07-24
I've made two sample, sandblasted(Fig1 Upper Left) and raw surface(Fig1 Bottom Left), with anodized color.
It seems the one with raw surface looks better, even better than the original hypergon(Fig1 Bottom Right)

It's not easy to mount hypergon on any shutter, even sinar db shutter would block some light when shoting 8x10. It seesm it is necessary to build a unique shutter for this lens to work with high speed film. Or maybe adding ND filters is an easier choice?

It's still a prototype, with modern AR coating
I'm still not sure how to manufacture that mini fan (Central ND).
Should be less then $500 (in CNC mount).
