Like my other goals Series L 77 mm in diameter, I chose this Canon lens protection to protect my new 85mm f / 1.8. FYI, lentils and other objectives Canon zoom is already treated anti-UV, useless to put a neutral UV filter to protect your "stones" ... This protection filter and no other that will make the most of its work without distorting the images. Of course this quality comes at a price. But what is it compared to your (your) aim (s) !? As for Amazon, pro transaction as always!
