I've used my FA* 80-200 with a ?Sigma? AF 1.4x, and my DA* 60-250 with the new HD Pentax-DA 1.4x. Both produced perfectly acceptable results for me (shooting hand-held). -- 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.
