Looking for the 200mm Hypergon fan lens for 20x24 camera. This lens is extremel y rare, about the diameter of a salad plate, and gives 24x28 coverage. Would al low me to use the camera at tripod height without DOF issues of 30" Goerz Artar. Are there available specs on this lens for an attempt at remanufacture thru Ed mund Scientific etc? Or is this an impossible wish.
