This is a composite of two captures with the Rodenstock 70mm HR-Digaron-W lens, each made with the back shifted up 15mm, and then with the individual captures shifted 18mm left and right, respectively. The result is two "side-by-side" 4x3 vertical images, with just enough overlap to allow them to be stitched together into a single 5x7 horizontal frame, yielding a total of about 270 megapixels.
The equivalent field of view on a "full frame" 35mm camera would be roughly that of a 26mm lens.
