The first thing I noticed about the K&F concept 82 millimeter variable ND filter, is that it was packaged super nice, and when I picked it up out of the box it felt like a quality product. It had a super nice metal finish and the two pieces glided across each other very smoothly. This was my first time using an adjustable ND filter on my camera, but I was always looking for the extra versatility and adjustable ND filter could offer versus a fixed ND filter stuck at one particular stop.

This variable ND filter definitely did not disappoint, I love how easy it is to slap onto my lens and it's so great being able to switch and adjust the power of the ND filter with a simple twist of the lenscap. In addition to its obvious uses an ND filter, I love the fact that I feel like my lenses are more protected when this is on them as well because the glass is not exposed to the elements. Overall, I am definitely convinced about using ND filters and adjustable ones more specifically, so I would definitely recommend this to anyone who's on the fence about getting an adjustable one. This one definitely does the job.
