Item received in good condition in a small branded box. My Action 6 has never been a slouch, yet these pocket-sized filters have given its images a surprising lift. Out on the prom at sunrise the footage looks warmer and more inviting, while the fierce midday light that normally scorches the lens has been tamed.The pack contains six clip-on filters cut from 28-layer optical glass. You get ND8, ND16, ND32 and ND64 for anything from three to eight stops of control, together with a circular polariser and a ¼-strength Black Mist. They pop on with a simple press to fit, held firm by a small anti-slip washer, so the filter stays in place even when the camera is bouncing about on the dog’s harness. There are no awkward screw threads and the unit still slides neatly into my compact protective cage.Changing ND strength takes moments, which lets me keep the shutter at 1/50 s for that pleasing motion blur while the children hurtle down the sand dunes. The CPL knocks back the glare on the water and the Black Mist adds a subtle bloom during sunset without flattening contrast.Robust construction, spotless optics and a genuinely useful spread of effects, all offered without a hint of colour cast. For the money, it is a solid selection of filters that can really help improve your results easily.
