I've seen and made K20 shots with similar noise performance. But as I said. I would not _expect_ it. I found that exposure was K10D even more critical at 800 ISO. That's why I'm very curious about exposure with K-7. I've played with one for an evening, but havent really tried it out. -- MaritimTim http://maritimtim.blogspot.com/ -- 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.
