I should think so. If you mentioned scratches on the front element though... To your question, SMC Pentax filters are highly reputed. Hoya HMC are good and affordable; I have even heard that going SHMC is falling for marketing ploy. I have also used Heliopan filters (for B&W) and was amazed by the smoothness of fitting. I only use filters for B&W anymore, and that seldom as they reduce my ability to focus in low light. Kostas
