You don’t need to spend the money for the Canon brand. They’re over priced as heck. Get one from JJC on Amazon for a fraction of the cost of a Canon unit. Fits exactly like the Canon. You don’t need the B+W filter either as they’re overly expensive. I use NEEWER MRC UV filters with 30 layer coatings and haven’t seen any color shifting or IQ degradation. They’re easier on the wallet too. Also at Amazon. JJC Hood https://a.co/d/0enqiL8E NEEWER MRC UV Filter https://a.co/d/0dxI6Uwx
