Well, what to say. Normal Chinese ND filter. More less does his job. Yea! There are changes in the balance of white. Yes, there is a vignette. Especially at high values. But... Better than without him. For the photo is a filter, very much even. For video so-so solution. Again! Better with him than without him. Long went, Long went.
Long waited for sending (almost a week), but quickly brought. The filter is happy.
