Assuming that the lens has no electrical contacts and is therefore a plain Kmount, go into "custom" menu, scroll down interminably to "aperture ring allowed" and set it to "permitted" - 2, I think. In _manual_ (M) mode, you can set the desired aperture, then press the (different on most models) button to stop it down and set the shutter speed. Repeat as required. If you try to use it in other modes, it will always be wide open. -- 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.
