A print of a certain size from APS-C is more enlarged than a print of the same size as 35mm. Thus, the "circles of confusion" on an APS-C image are more enlarged than those on a 35mm negative. Thus they need to start out smaller on APS-C to yield a print of identical sharpness. If you consider a 30 micron circle-of-confusion on a 35mm negative to be "just sharp enough" when printed, then you need a 20 micron circle-of-confusion on your APS-C sensor. -- 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.
