Hi all, I picked this up from Clive Russell on the Large Format list. http://www.f32.net/Services/Equipment/Cameras/hunter-penrose.html
What an incredible piece of equipment! Of course, I'll need to wash my mouse with soap for referencing lens equipment on this list, but I thought that with a bit of imagination we could imagine replacing the lens with a 1.778mm pinhole at f/1012 and do some interesting work... Keep on pinholin' as Tom would say, Guy
