I shoot vlogs and wanted to experiment with manual settings outdoors; and it was suggested by other Youtubers to try using a variable nd filter for video shooting to help get a more cinematic look. I didn't know what to expect and didn't want to drop too much money so I gave this one a shot. I bought this particular fader because it was available and recommended by Amazon. Honestly it works very well. I've used it on video shoots and it helps me get the exact settings I want. I can easily get the fully open aperture and low ISO in broad daylight. Being variable I just have to rotate to change the setting rather than changing separate fixed nd filters. The image quality looks great as well, very sharp. I'm not sure if there is any color change as I don't notice it. The only thing I wish it had was some indicator to tell you what density it is at other than just line markings. But it isn't a deal breaker since I just rotate until I get the right exposure settings anyway. Just be careful of rotating past minimum or maximum as you do get that 'X' across the image that people talk about. I think it's prevalent for all faders anyways. Also I wish I could put a lens cap on it since the outside isn't threaded so the cap doesn't stay on. Other than that the build quality seems very good.Overall it's a great filter to experiment with and for its low cost it's definitely worth trying out.
