1 - Sacrificing maximum resolution at the plane of focus can be a worthwhile tradeoff for getting greater depth of field: You lose a little sharpness in the center of the DOF but gain it everywhere else. (Though above f/22 the losses pretty much overwhelm the benefits everywhere.) 2 - Smaller apertures allow longer shutter speeds, which may be more desireable in some circumstances. -- 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.
