Rob, I was a little surprised to see the same thing you did. It looks like "veiling glare" to me. I associate it with older single-coated lenses. We all know that Pentax has wonderful lens coating technology; maybe there is some internal reflection in the inner lens barrel that only occurs when the aperture is wide open? --Mark -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
