【Hard Stops Design】This special design features a clear stopping point that provides tactile feedback with a 'click' sound when you adjust the gear, so you can know you've reached the correct position without looking at the scale 【True to Life Color Reproduction】 The true color variable ND filter solves the common problem of partial yellowing and color shift, ensuring the true color of images and videos 【No Black Cross Variable Filter】 This limited variable camera lens filter provides 5 stops of exposure adjustment. Simply rotate the filter to switch between ND2, ND4, ND8, ND16, and ND32 settings for precise control over the amount of light entering the lens. This allows for better control of exposure and shutter speed when shooting rivers, waterfalls, light trails, and more 【Multi NANO Coated HD Optical Glass】 The ND filter, with 30 layers of NANO coatings on both sides, reduces glare and reflection while effectively protecting against water, dust, oil, fingerprints, and scratches for extended use. The HD optical glass material helps capture vivid colors and manage contrast without losing image sharpness 【Lightweight Aluminum Frame】 Firmly sealed with an ultra-slim aluminum alloy frame, the filter delivers the desired effect with ease. The CNC precisely machined knurled ring ensures a secure grip for easy filter mounting and removal
