I have acquired a Hermagis Aplanatique that is 1200mm or 47 inch focal length. Other than turning my living room into a camera obscura, what format would this cover, if they even made film larger than 20x24? I'm roughly guessing it would cover 40x40?
An Aplanat is basically a Rapid Rectilinear, if that is what this lens is it would cover like most any R-R. NICE find! I'm envious!
