Could not find the difference between filters
Recently I purchased Hoya 62mm Evo UV (0) Filter through eBay.
After purchase I got an email confirmation and checked that mail and found that they have sent HMC-C filter instead of HMC-O. I googled the difference between two of them. But I didn't find any and about them.
Did anybody hear the difference between these two filters? I yes Please explain me and also tell me the suggestion that, can I change already ordered filter? Many Thanks for your help in advance.
