Verified Purchase(What is this?)
This review is from: Hoya 77mm Pro-1 Digital UV Screw in Filter (Accessory)
After suffering with this filter for over 12 months in ignorance of other reviews (external to Amazon) I was finally so disappointed with the appearance of this filter after cleaning that I did more research and found it wan't just me who had this problem. I want to protect a lens but I think it is reasonable to expect one of the main requirements of the filter is that you can clean it and restore a clear piece of glass. In fact, no matter what method I used it generally produced worse results the more I tried to clean it. I don't know the technical cause for this that apparently other manufacturers have mastered a solution and I am now ordering a B&W filter - based on good comments about the ability to clean it. Hopefully this time it will be money well spent.
