I read somewhere that a brand of process lenses from a manufacturer I can't recall, that their lenses were so popular or worked so well or were so well made, what ever, that they were put into use as taking lenses. They were so well regarded that the manufacturer started to put them in shutters, Ilex as I remember, and sold them as primary taking lenses.
Any clues to which manufacturers or manufacturers this was? Schneider, Goertz, Cooke, ?????.?
