77mm Magnetic Variable ND8-ND128(3-7 Stop) Lens Filters + Magnetic Filter Basic Ring Kit with 28 Multi-Layer Nano-Xcel Series
SKU: KF01.1980
I use this both in the studio to drop my F-stop, and for Video. Used it on professional shoots with my RED, and smaller shoots with my Fuji. Haven't pixel peeped it, but during my edits, I notice no desegregation or X. The best variable I've seen, and absolutely a steal for the price.

For the money you can't beat this product, especially for video. The variable control allows for a much better control over lighting conditions that gain (or iso) alone. Love it and would recommend when you need to shoot in direct sunlight.

The darker version of this is utterly indispensible for LOG video with high ISOs forced by the camera, combined with fast lenses you'd like to open up for depth control/"bokeh". And only the wildly expensive PolarPro has a similar option. And while I suppose the PolarPro might be somehow better - I'm simply not rich enough to find out! In the meantime the K&F has served very well. I use this primarily on a Fuji X-T3 with f1.2 and f1.4 prime lenses, shooting F-LOG at the required minimum 640 ISO. Secondarily on a Fuji X-H1 (800 ISO LOG!) and even a Nikon D750 for occasional stills.** Hey K&F! Do you read reviews? I wish you offered the dark version in smaller diameters (e.g. 62mm) as I'd get another to use with the majority of my prime lenses with no step-up ring. **
