It is good
The ND filter is good but the vignette is obvious at a certain degree, not sure if it is how ND works of the filter itself

Did not come with box foam shown
Filter performance appears fine. For some sizes, the protective box does apparently not include the additional foam housing to keep the filter secure. It slides around in the box.

安。
安いので試しに買ってみました。工作精度は問題無し。操作感も良いですよ。ズームレンズの広角側で使うと外周部が暗くなる傾向があるので、そこだけ注意。※追記 晴天の屋外で使用してみたところ、フィルター内で変な反射がある(緑色)コーティングがダメなんだろうなぁ~。順光なら何とかなるけど動画の場合は乱反射に気を使って順光でばかり撮れる訳ないので、国内の安心メーカーのND8~32だけ買うことにする。

Would be better if the filter stopped at max and min
The filter does not have a stop, it will continue to spin all the way around. Though it does spin freely, taking the camer in and out of a bag/case may change the filter intensity. Otherwise it allows for much lower f stop. I use this while filming outdoor shots.
