This is great to try, by cons, expected perhaps a container that will prevent scratches after use ND8 (first), I already have a scratch on the filter despite great care. I think the cover (yet convenient) supplied with filters does not protect them enough. I ordered in by-side container for my BEFORE filters scratch all others. As much thinking before the order happens if you do not want to have filters unusable very quickly. Otherwise, the filters themselves are pretty cool, I have tried the ND8 for now by cons.
