If you can read it off the focus ring, why can't you read it off the motor position? This situation does give me an idea for a handy use of the fx button: Only search for focus within the current range. If I'm trying to focus on something at 0.8 of the hyperfocal distance, the next time I press the shutter don't bring the camera in to minimum focus. If I'm using my macro to focus on something six inches away, don't give me perfect focus on the fence twenty feet back. -- Larry Colen l...@red4est.com sent from i4est -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
