I don't know what the cause of it is but the same effect can be observed when shooting high contrast subjects using the A50/1.2, A/FA50/1.4 lenses wide open so I assume is more to do with the lenses optical aberrations and internal wall reflections than coatings. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://picasaweb.google.com/distudio/PESO http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
