Remember that lens resolution lessens as you approach the edges. I seriously doubt the 1DsmIII comes close to outresolving its lenses at the centre, but even the 5D had issues with this at the edges. It's likely that the 1DsmIII has such issues with more lenses and further away from the edges. -- 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.
