I'm not all that much for manual focus, but I definitely appreciate the brighter image of the pentaprism. So that wipes out a big potential cost advantage of Nikon/Canon (not worth getting one of their cheap cameras). -- Hugs and backrubs -- I break Rule 6 http://rule6.info/ <*> <*> <*> Help a hearing-impaired person: http://rule6.info/hearing.html -- 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.
