Well, in the world where the laws of physics and optics apply, that is nothing to do with the diopter. If there is a sharp image on the focussing screen, but not at the same point as on the film/sensor plane, that's caused by a problem with the placement of the focussing screen. All the diopter does is to make it easier for your eyes to focus on the image on the viewfinder screen. A poorly adjusted diopter can make it impossible for you to see *anything* in focus, but it can't make part of the image on the focussing screen appear sharper than it really is. -- 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.
