I have launched my medium format Petzval portrait lens project.
It is made by original Petzval scheme, not improved or re-designed. Here is the link to the Kickstarter project page:
Please, share your opinion or support the project if you like the lens.
Interesting lens. Looks better than that Lomo lens, which isn't a real Petzval lens as it seems (just some swirl in a metal tube?).
And your lens fits a medium format camera as well.
Good luck with your project!
