I don't get what you mean by the lens "always" being wide open. If you have a smaller aperture selected via the aperture ring, the lens will stop down when the shutter trips - regardless of whether or not you've metered for that possibility beforehand. Or am I missing something? -Charles -- Charles Robinson [EMAIL PROTECTED] Minneapolis, MN http://charles.robinsontwins.org -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
