ND FILTER
Reduces the amount of light entering the lens, thus decreasing camera shutter speed. Useful for situations where motion blur needs to be created (rivers, waterfalls, moving people) or large apertures must be used with flash to avoid overexposure.

K&F Variable ND Filter- Hard Stops & Best Bang for Your Buck
When I ordered the K&F variable ND filter, I wasn’t sure what to expect in terms of quality and the coloring that would be achieved when my images were rendered. However, the colors do not shift at all, and I was pleased with how nicely they pair with the Sony A7iii and A7riii. As an owner of both Polar Pro and Tiffen filters, I must say this filter is a cost-efficient product, coming in at half the cost of the Polar Pro filters I own. Even better, is that this filter has hard stops so you don't get that X when you go beyond the filter’s limit. If you're on the fence about ordering this product, I highly recommend trying it out. Below, I've added a couple images where the K&F variable ND filter was utilized- one shows the filter on my Sigma 135mm f/1.8 Art, and the other demonstrates a portrait I took while using it.

Outpaces much more expensive filters.
The first thing that stands out is the nice packaging that it comes in. Definitely meant to keep the ND filter safe. I tried a few video clips and some photos with the filter attached to my Zeiss 24-70mm lens. The image quality was very good and the filter feels really substantial.I'll post some images after uploading to my computer.
Outpaces much more expensive filters.

This ND filter is amazing for waterfalls
I don't normally write reviews but this item brought me so much joy I had to. One of my best purchases ever. Went on a hike to a waterfall and was able to get fantastic photos in midday sunlight. I get to eliminate my half a dozen other ND filters because this single filter does all that and much much more.One downside is it is too thick for my lens hood to fit over the filter. Doesn't matter. The convenience and performance vastly outweigh that downside.

yes, on both sides of the filter

For the Nikon 7200 you need a filter in the size 67 mm, this also applies to all lenses.

It's better to buy a cleaning fluid for lens filter.

Dear Customer, it could fit your Sigma f2.8 24-70mm lens with 82mm threads.

All the filter could satisfy your need for the outdoor music videos in bright sunlight. but the nd 2-32 and 8-128 could be much better. if you like it a little bit darker, then nd 8-128 will be your choice. If you have no concern on nd stops, then nd 2-32 could be your choice.
