As the title suggests, what lenses of focal length 210mm to 270mm will cover 14x17/8x20? I mean really cover, with detail in the corners, not just illuminate. Will the 240mm f/9 Zeiss Dagor do so? What is its rated image circle at f/22? Where there ever SW designs (like Super Angulon), with 100 deg coverage made in such long focal lengths? I can vaguely recall a SW 300mm Fujinon but this may not have actually existed? Seems that type of design might be useful in the 240mm+ focal lengths but they top off at 210mm...(except for that possibly imaginary Fujinon! Has anyone actually SEEN one?). Thanks!
