Like you, I've been looking to change over from screw-in ND filters to a square system to utilize an ND grad. My research led me to the K&F system and your video. I was so happy - and surprised, that your video is the only review I've watched where the filter kit wasn't supplied free of charge by K&F. They must have sent hundreds of them out for review for marketing purposes. Anyhow, i thank you for your honest review of these filters Cheers and I hope your recovery continues well !

Great video. I normally use magnetic round filters but when I go to the coast I have the K&F square filters. When you need ND grads you need them.

I've been happy with my K&F magnetic, but I don't use filters as often as I probably should. Years ago I had big plans to build up a good sized Cokin filter collection, but instead it was a small collection of about 4 or so. Haven't used it in years.

Hi, I like your videos but this one has mono sound only. I do not know if that is just a setting on your wireless mic system. But it is a bit anoying to listen to with a head set on, as I only get audio on one ear then. But it can be easily fixed in post production and if you do not know how, feel free to answer me back And I'll try to help you figure it out. I got to much spare time on my hands. Anyway the bit of this film where you open the box of filters is not affected, but perhaps you used a diffent mic or a built in mic in your camera or phoen then?
