I have posted this information earlier, but the Kickstarter project, aimed to create medium format Petzval lens is active and I'm looking for support of new backers.
I have completed building of prototype Petzvar lens with Hasselblad V mount, that will be compatible to Hasselblad 2000 or 200 camera with focal plane shutter.
Now the Petzvar is compatible with Hasselblad 2000 or 200 models and Pentacon Six mount cameras. It can be used with Mamiya 645, Pentax 645 and Contax 645 via available adapters as well as with almost any 35 mm full frame SLR with adapters.
Here is the link to Kickstarter page, there are more details and images there:
