Yes, I have an "official" Tamron rear cap with this defect. I have put a big bright white line on the bottom of the cap which I can use to line up visually with the red dot. It helps, but is still a pain in the rear! I have NO insight as to why they do this. -Charles -- Charles Robinson - [email protected] Minneapolis, MN http://charles.robinsontwins.org http://www.facebook.com/charles.robinson -- 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.
