Certainly not a top class filter, but to protect the objective lens from impact or dirt always sufficient. Both the frame and the glass make this the impression that she also similar shocks endure, so that the protection is definitely guaranteed. For filtering of UV light, I can not say anything; but with digital photography it does not matter anyway. Because I had the impression that despite filter dust came on the lens, a point deduction. The bottom line (for the money) but a useful filter.
