【Usage】The Variable ND filter allows you to shoot wide-aperture lenses in bright light without overexposing and shallow depth of field while under lighting conditions that exceed the shutter speed capabilities of the camera. A good partner for you to record movement in subjects such as waterfalls, vehicular traffic, seascapes, streams and clouds.

【ND 2 - ND 400】2X to 400X filter factor provides an exposure reduction of 1- 9 stops. You only need to carry one ND filter with you to get a variety of darkness levels.

【X Cross】Due to the design of the filters, as you approach the maximum ND setting, you can get a cross pattern across the image. This is remedied by dialing the ND setting back a bit.

【Multi Nano Coating】16-Layer Nano Coating makes the filter anti-scratch, anti-fingerprints, anti-static, oil and water-resistant. The filter is constructed from high quality Japanese glass for increased optical clarity and color fidelity. Slim design with 0.28” aluminum frame helps minimize the potential for vignetting.

【How to choose the right thread?】Compatible across all lenses with 55mm lens thread. Please verify your camera's lens thread size based on “Ø” marking on lens barrel or underneath lens cap before purchasing. For this 55mm ND filter, the lens cap/hood should be 58mm.

【High-end Japanese optical glass】K&F Concept variable neutral density filter made of high-end Japanese optical glass, double-sided multilayer blue coating is conducive to waterproof and dustproof.

【Reduce Exposure】ND2-400 Reduces light intake from 1 to 8.66 f-stops, which is especially suitable for rivers, waterfalls and other waters, especially under strong light.

【Double anti-reflective coating】Allows the use of slow shutter speeds on high speed films or digital cameras to record movement/image blur in waterfalls, clouds or any fast moving subject.
