Plus, for telephotos, the "crop factor" works to the advantage of APS-C. It's a lot cheaper to buy a 200mm/f2.8 or 400mm/f5.6 than it is to buy a 300mm/f2.8 or 600mm/f5.6. -- 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.
