The 1.5 crop factor doesn't affect the focusing distance of the lens. The portrait fills more of the frame at the same distance, so you may have to back off just a bit if you're already filling the frame on the PZ-1. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
