[1] Does this mean it might be correctable? [2] When you say "at a 45 degree angle, do you mean relative to the focal plane, pointing away from the lens? How far away should the yardstick be? What will be the indication of back- or front-focusing when I do this? ------------------------------------------------------------------------------------------ Eric Weir Decatur, GA USA [email protected] -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
