Just wondering about this lens. Does it cover a full 4x5 view? I intend on using it on a Graflex Speed Graphic 4x5. The seller I think was using a 2x3 Graflex, but he was also advertising it for 4x5. His comes with a lens board and I'm not sure the smaller camera uses the same lens boards as the Speed Graphics. Also is this a decent lens for its day? My main use for it will be landscapes or just general outdoor use. Also are these lenses coated? And when were they produced? Any info would be great.
