I love this variable filter that I use on my Nikon D5600 DSLR. I’m an amateur photographer, kind a “B-minus” student on the technical side of things. But, I do enjoy, and am getting fairly good at, various long-exposure techniques including ICM, which can lead to blown-out/too brightly-exposed sunny outdoor shots. Learned about ND filters in my photography class. Apparently, you can take your shutter speed and aperture settings and pump them through an algorithm to determine where to set your ND filter, or which non-variable filter to use. Too complicated for me. When I set my exposure length and aperture settings with the ND filter at its “Min” setting, then point my camera at a sunlit subject, my camera will flash “Subject Too Bright”. I just start slowly rotating the variable ND filter’s ring toward “Max”. As soon as that “Subject Too Bright” message goes away, I know it’s OK to release the shutter. Perfectly exposed shot every time with this inexpensive variable ND filter.

Works exactly as described, but the outer ring (ND portion) of this filter is just wide enough to keep from using the lens hood. I rarely use my lenses without the hood they came with, but will have to do so every time I want to use this filter.

IMpresionante lo que se logra con mucha iluminación, es un accesorio imprescindible

Very nice when shooting sports outdoors in the sun. Allows me to take videos at a super low shutter where too much light is coming in.

One of the best purchases I’ve made in a long time. I was out in Phoenix, Arizona and their sun is different. I love the glare reduction and the ability to adjust on the fly if the shot is still too bright. I will be purchasing these for all of my leness.

No problem so far. Have yet to test it in difficult lighting situations.

I got the 77mm and the 82mm and as far as budget VNDs go they're decent. But why on earth would you label them this way? On the 82mm MIN is the lightest point and MAX is the darkest. It's the exact opposite on the 77mm. Why??
