I''ve shot at least 500 frames with the DA 16-45, probably quite a few more. And i've used the standard hood with all of them. Remember, this lens is 16mm at the wide end. I suspect Pentax has optimized the hood. However, I should point out that I always "flag" the sun with my free hand whenever I think it might be a problem. It's a good practice. Paul
