Especially in dim-light conditions. Now I understand the differences, and why "open aperture" would be preferable if using a split image focus screen. And I know how you do "open aperture." Are there other advantages to "open aperture"? Don't understand how you do "stopped down" or what the advantage is. ------------------------------------------------------------------------------------------ Eric Weir Decatur, GA USA [email protected] -- 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.
