For the price this is a great nd filter, The only downside is that you get a slight green colour cast but nothing you can’t fix in post production, otherwise great filter.

Great quality ND filter compared to price. You should get one of this ND filters if you are a video maker.

One of the greatest Variable ND filters for its price range.Of course, If you are looking for Zeiss grade accessories, pricewise it will cost you something 10x times more and when talking on such precise and high grade attachments for your lenses, Variable ND filters are not the options - you should have bunch of fixed ND filters, with finest and highest grade glass and coating.This one does same if not more as similar Variable ND filters for $50-70, Slim design, so if you stack it on top of standard protective UV filter, it doesn't generate vignet.Glass is fine and high grade - no significant distortion for most $700-$1200 lenses, which I think is not bad, comparable to lens distortion values itself. Again, if you are such picky for distortions and using Zeiss Otus or even Milvus Primes for over $3000, then you should afford getting fixed ND filters from same Zeiss :)If you have DSLR, your backpack is almost heavy enough, so instead of carrying bunch of fixed ND filters for regular outdoor shootings (and weather is coming up and more bright sunny days we'll have :) ), Variable ND filters are desirable lens attachments and for most of APS-C and Full Frame cameras with sensors common 24 MP sensors, this one is one of the optimal solution.BTW, after great medium range tripod from K&F Concept, this is another camera accessory I've got and I like both - great manufacturing quality, nite and clean, functions as it should be and excellent Price/Quality ratio....

A good starter ND filter. It's helped me out on several shooting occasions. Would recommend for someone looking for something basic that does the job.

I am using this ND Filter for my sony alpha a6000 with kit lens. product quality is very good but unfortunately it doesnt seem to fade properly with the kit lens I have. Check out the picture. Maybe I dont know how to use this filter. Any advice? I have given this product 4 starts only because of the quality of the build.

Feels like really good sturdy quality. Smooth turn and nice gradient for the amount of filter. Screws in nicely to front of lens.

You get color cast, but it's a lot better than Neewer, which came broken

Bought this to photograph the eclipse. Worked well for that. 4/5 due to the lack of stops, and lack of marks/etching to indicate approx ND level. Like I said, worked well, but if you want any idea of what your actual exposure values are you'll need to mark it ahead of time at a minimum.

Great price and product. Good Job K&F!

I have to say that I was disappointed at first. I looked at the filter and it had smudges that looked nearly like scratches. However, I thought, well maybe this will clean off. To my surprise, it did clean off! The filter itself is excellent and does exactly what it says in the description. It's a great variety shot filter with the ability to literally change the light entering by a circular polarizing lens array.
