In this video I make a comparison of the K&F Concept ND8-2000 variable ND filter with the PolarPro 2-5 Stop variable ND filter. Both have a thread size of 82mm. I compare them in terms of quality, price, color shift and vignetting. Since the polar pro filter is 6 times more expensive than the K&F filter, this should be obvious - but it isn't ;-)

I used both filters with my Sony A7siii and filmed a commercial with the K&F Concept filter, which I show at the end of this video.

Here's the K&F filter on Amazon: https://amzn.to/3M9rqj3
