The Rodenstock APO-Ronar 480mm f/9 is the longest focal length in the APO-Ronar process lens range, with a 396mm image circle covering 8x10in with some movements. With a 67mm filter thread, the four-element symmetrical Dialyte design remains remarkably compact for a 480mm lens. It is designed for large-scale reproduction work but can serve as a lightweight long focal length option for 8x10in landscape photography when stopped down.
