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.

For the money It's good enough
It is definitely a learning curve to use Variable ND filters so sometimes it's a battle but most of the time I get great shots. I took these pics with a Panasonic G85 with Panasonic 25mm f1.7 Lens (ASIN B014RD6RC0) with stepping lens kit. But I normally use the ND Filter with the Kit lens from the G85. Would I recommend it? Yes, but only if you want to learn when and why to use ND Filters in the first place. You can't just buy ND filters and expect miracles. Get to learn how to use it, when and why and you're set. Once you learn, you will end up loving these filters.

Awesome; Must have for video
I had a smaller diameter of this product for a different lens, so when I got my new lens the first thing I bought was this ND filter. It is incredible. And this one had little dots along the edge, as well as text that read "Min" and "Max". This was super helpful. My only complaint about the smaller ones was that you couldn't tell how far was the maximum and minimum, and this model has solved that issue. I don't go anywhere without this filter. I will be buying a K&F Variable ND filter for every lens that I get from now on.

OK for the Price
The filter seems to be fairly well made and sturdy for the price. I saw warnings on other reviews about the possibility of uneven lighting and vignetting on photos. That being said I decided to try out the filter anyways. I took these photos on a Nikon d5600 using the 58mm nd filter and a step-up filter on my 55mm kit lens. Overall the quality is decent, and if I was looking for a quick fix just so I can enjoy a little better quality in my photos I would Pick this filter. But if you are looking for professional quality that will bring your photos to the next level, this is not it.

All in all amazing
I absolutely love it! In the first picture I tried the darkest setting this filter has because its extremely bright outside and with white flowers it seems even brighter. The first lens I bought was too small and the company helped me with that almost instantly! And the quality of the lens is even better than the customer service! The original variable lens I bought was from another company and the darkest setting just didnt seem to help whatsoever.

Did what I wanted
I may have to play around with the settings but It didn't do too bad of a job. I did not notice any ghosting effect like other reviews said it had. I had gotten the filter just in time for my trip. It pays to read reviews and sometimes it can be a gamble what you buy. I would definitely recommend this filter. It did end up doing what I wanted to. However it will not fit in my 300mm zoom lens just on the 18 55mm wide angle lens. Still not a bad deal.
