The vignette with this filter is a serious issue and I wish that I had read about this issue before purchasing it. You can see the issue in the attached photo.

I purchased this because I didn't want to spend hundreds on other options out there and this one works very well. A little green cast but overall not too bad. It has saved me when I film outside and want to get the best looking background compression in the sun. Comes with a nice case and its built very well. Love the indicators that tell you how many stops you are adding. Would purchase again.

The filter is of exceptional quality. It’s sturdy, stays in place, and comes in a nice case. The ability to adjust the amount of light that enters your camera on the fly is indispensable. This is a useful tool to have for any photographer.

Threads seem uneven, squeaks and gets tight on lens threads, over all good image qualityDidn't break the bank so I would recommend for a beginner kit until you figure out if you actually need something better

I have a Sony A7III with a couple of the Tamron lenses they recently release, 67mm thread on both. I used the ND for the first time on a shoot in broad daylight mid-day and loved the results. Best part is being able to dial in very easily the amount of stops I need to make the zebras go away. Smooth operation and sturdy construction. The only negative is that the lens hoods no longer fit once the ND is on. Not a deal-breaker but be aware.

I shoot with the Fujifillm X-T3 which arguably is the best video camera under $3000. However it lacked the variable ND filters that you would find built in to more professional video camera. I needed some more motion blur and lower my exposure when shooting video and this does it amazingly without any noticeable loss of details and colors. For the price this is a very valuable tool in my arsenal. The build quality is really nice with an all metal construction. The ring itself is smooth and allows for a nice variable exposure change. I really dig this ND filter and I think anyone should take a look at this since the image it produces are pretty clean.
