Look at the MTF diagram of most any lens designed to cover a FF lens and note the fall off in resolution/contrast 2/3 from the centre of the frame, the APS sensors very conveniently disregard this area of poor performance. -- Rob Studdert (Digital Image Studio) Tel: +61-418-166-870 UTC +10 Hours Gmail, eBay, Skype, Twitter, Facebook, Picasa: distudio -- 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.
