I own a Canon EF 17-40mm f/4 USM L. But after a few months of usage, I notice that the inner lens hood is sucking up a lot of dust. And I find it very difficult to clean it.Do anyone have any idea how to remove the dust stains?[a href=\"index.php?act=findpost&pid=126554\"][{POST_SNAPBACK}][/a]
You say stains, and I'm a bit perplexed... on the inside of my lens hood there's a lot of "lint", which comes out quite well if I remove the hood and use a lint brush.Because it's felt, I'd look to using a clothing brush (different from a lint brush) and see if the stains go away. Not sure what would stain it though...--dilip[a href=\"index.php?act=findpost&pid=126586\"][{POST_SNAPBACK}][/a]
Its something sticky, and I have no idea where I got that.[a href=\"index.php?act=findpost&pid=126674\"][{POST_SNAPBACK}][/a]
