I think the black marks could be the little "hair" from the same material used on recent Pentax hoods. Mine has the same problem too and I had to remove the rear element to blow them off (3 tiny screws on the lens mount). I would say they should not choose that material in the 1st place (just not very practical). But you would never know what they were thinking. regards, Alan Chan _________________________________________________________________ Join the world�s largest e-mail service with MSN Hotmail. http://www.hotmail.com - This message is from the Pentax-Discuss Mail List.
