Versatile ND Filter for my Action5
I’ve been using the K&F Concept Push-in Fit Variable ND2–32 Filter on my camera lenses and it’s been a really handy addition to my gear. The push-in design makes it super easy to attach and remove—much faster than screwing filters on and off—and the variable ND range gives great control over exposure in bright conditions without needing multiple filters.The image quality stays clean through most of the range, with good sharpness and no obvious color shift. Adjusting the filter feels smooth and precise, which makes it easy to dial in the exact exposure you want for video or photos.One thing worth mentioning, though, is that like all variable ND filters, you can run into cross polarization (the “X” pattern) at the extreme end of the range if you push it too far. As long as you avoid maxing it out, it’s not really an issue. Overall, it’s a solid, easy-to-use ND filter that works well and saves a lot of time when shooting outdoors.
