Reliable quality from K&F Concept
I picked up this K&F Concept ND filter set to go with the Action 6 and it’s exactly what I was hoping for. Everything feels solid and well finished, which is reassuring when you’re swapping lenses on a small action camera.Fitting them is straightforward. The screw-on design matches the original lens cover, so they go on smoothly and sit securely once in place. I much prefer this style over clip-on filters, especially for outdoor use, as there’s no worry about them shifting or coming loose mid-shoot. They also work fine with cases and accessories, which is a big plus.In use, the different strengths give plenty of flexibility depending on light conditions. Bright scenes are much easier to manage, highlights stay under control, and footage looks more natural overall. Image quality has stayed sharp, with no odd colour shifts or softness that I can see. The glass also seems to resist water and dust well, which makes them practical for real-world shooting rather than just ideal conditions.The set covers all the essentials and feels built for regular use.
