I have tried, and own, different grades of black diffusion filter. I think for its subtle effect, this 1/8 filter is my favorite. The smooth look, and highlight diffusion that you get with these filters, is either an acquired taste, or a specific characteristic that you're looking for in your shots. I personally don't use them all the time, but it is nice to bloom the highlights in certain scenarios. The 1/8 filter is very subtle in the daylight, but I found excels at night. You can of course, use it with decent effect during the usual golden hours, as the intensity of the highlights then, may be more visibly changed by this filter, photographically. In the daytime, with the sun right above you, it's hard to notice much of a difference. For video, it does an interesting effect, and may be something that you can apply to specific scenes, or just to unsharpened some of the digitized look from most cameras. Quality of the filter is very nice, made of good materials, and with nice coatings. It comes well packaged, in your standard plastic case, as well as included sealed microfibre cloths. It is affordably priced, and performs very nicely, for that price range. It doesn't in any way appear cheap to me, and like mentioned before, I do like the subtlety of this gradient. It's certainly good for the camera bag, and would be interesting to try with some golden hour portraiture. For video, I'd say it's limited to dreamlike sequences, and better suited for golden hour, and night time. All in all, I'm very pleased, and if you're looking for a 1/8 black diffusion filter, this one is a good choice.
