This is based on the size of the circle of confusion allowed, usually expressed in absolute terms, e.g. 1/200 inch, or as a ratio of focal length, e.g., f/1720. Not knowing this, I often position the inf. mark on the next aperture up just to be safe, e.g., on f5.6 when shooting at f8. Stan Yoder Pittsburgh
