Variable ND filters are a great accessory that solves a lot of situations. I use this filter the most...however, the one I had was pretty bad. That's why when K&F Concept contacted me I didn't hesitate for a moment. And here I bring you a REVIEW of the variable ND filter ND2-ND32 from the K&F brand and I explain its main uses (at least for me).
