Do not, have a single doubt about its quality.
26 May 2017
From opening the box, till installing it on the lens, I got an idea about the build quality. There was no spaces, between the filter and the lens , also not between the filter and lens cap.
Very easy to install and remove. Can be cleaned easily also .
No, matter how good the quality is, Still You should spin the filter slowly, during installing. As forceful, spin may damage the threads.
Not, noticed a much difference between the pictures with and without it, and don't expect also.
But, this will surely save the lens from scratches and, water drops. So it is a small but rather very good investment for the lens.
