You're right, Bob, didn't know that the old Hypergon was such a unique, modern lens !
I had a look and found even a 75mm Goerz Hypergon and the author says: "One of the greatest and coolest lenses ever made, It’s the widest angle lens ever made that covers 8×10 with movements." !

My apologies, Birna !
