    • Doesn't disappoint
Style: ND0.9 (3 Stops)
Best bang for your buck ND filter. Don't pay $300+ dollars for a filter when these work just as well if not better. I've never had a bad experience with K&F products. No color degradation at all with these filters. No noise at all with these filters when you have to crank up your ISO for dark shoots. Great quality glass, scratch resistant and has 26+ layers. Amazing, amazing for the price. I plan on buying more of these filters from K&F. My next purchase will be the blue filter and black mist. These filters are a must for anyone wanting to make quality videos. ... show more

    • Feels and acts like a 300$ product
Style: ND0.6 (2 Stops)
Was skeptical because of the price but it has some weight to it , comes in a beautiful leather case and fits into their mini matte box with ease so you’re not going to beat this item, I can’t see paying upwards of 200-500$ More for filters of this SAME type sorry

    • Quality glass for high end production value
Style: ND0.6 (2 Stops)
Using a variable ND filter screwed on the front is easy but is not always the best. This glass in my matte box provide the ND filter look of a professional.

    • Love it
Style: ND0.9 (3 Stops)
I'm gradually getting into matte boxes and square filters such as this. I've had great experience with K&F's circular filters that thread onto the front of my lens, and this square filter by them meets my continued expectation of excellent quality from K&F. It fits well, albeit tightly, in my Neewer matte box, though I believe this is more on Neewer's side than K&F's side. The 3-stop ND filter works great. I don't notice any significant color change. Obviously, there's no X issue as it isn't a variable. I love it. Carrying a square filter around is much more cumbersome than a round filter, but it's a learning experience. ... show more
