I bought the filter in the first place to protect the lens and therefore wanted to first have the güntsigste product. What I have not thought of, is that the whole light spots, which filter out the lenses of the lens usually can be seen through this filter back in the picture. This is particularly annoying at concerts! During the day, however, these spots fall on hard. From the UF filter effect I've really noticed anything. Whether with or without a filter - the pictures look relatively the same.
