This is serious stuff
The most beautiful package I had this past Christmas. Very well made and superb quality filters. But the carrying case was amazing. I mostly use this for slog 3 video footage and works like a charm. Very hard to print a finger in. I have others which I need to clean them up on every use.

Cine must have
Surprises by the quality of the filters and packaging. Couldn't be more happy, I can now use my matte box and have that cine look.

Affordable with no drawbacks
I was unsure when I purchased these at first due to the mixed reviews I was reading online, then they came in and started using them with my small rig pro matte box my wife had bought me my bgh1 cinema camera and I can say they definitely make a difference when filming in the best kind of way and come in this neat packaging it’s really gave me the most bang for my buck.

Take your cinematography to the next Level
The 3 stop filter stays on my camera at all times, indoor or outdoor. I film mostly indoors, but the filter allows me to keep a super low aperture (around 1.8) and create a really nice cinematic look. I'd say it's definitely elevated my videos without having to do anything massively technical. The price for 2 of them is hard to beat. I recommend it.

Everything great but delivery
I'm not sure how I feel about this product. I love knf nano series filters and sadly these came damaged. Chips on the sides. I was going to ignore it but it did show up on my wider lenses footage. It was hard to accept these came like this. The positive? Amazing like their circular filters. Finally got to the "matte box" level of filmmaking. These are heavy but are so good. 64 was the sweet spot for midday sun. Put the actors in city building shade and blasted them with our lights. These just gave what we needed. I might see if I can just get a replacement. Love this brand, but it was hard to accept this purchase as it was.
