Just to clarify, I meant top right as the image is presented, actually top left of the properly viewed image. At 70mm/f4 it is much worse. Can't be bothered to download any of the other images. Most of the problem @70mm seems to be due to tester hyperexcitement. Always thought of the Japanese as rather more phlegmatic than that..... ----------------------------------------- Email sent from www.virginmedia.com/email Virus-checked using McAfee(R) Software and scanned for spam -- 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.
