【Variable ND2-ND400 Filters with Putter】This variable ND filter helps control the amount of light reaching your camera sensor with 1-9 stops available. Simply screw this ultra slim filter on your camera lens, then hold the putter to rotate the filter to accurately adjust from ND2 to ND400 with ease. By reducing exposure brightness, it enables you to better control shutter speed, well suited for capturing river, waterfall, light trails, and other dynamic motion blur | 【Quality Build with HD Optical Glass】Made of premium HD optical glass, the high definition ND filter delivers cinematic photo look without distorting image quality. The 30 layers of double sided nanometer coatings, with 0.1% minimum light reflectivity, reduce flare and ghosting while protecting the filter against moisture, oil, dust, and scratches | 【Aircraft Grade Aluminum & Ultra Slim】Aircraft grade aluminum alloy frame makes the filter lightweight and ultra slim, 0.37"/9.5mm thick (including thread, 0.29"/7.4mm thick excluding thread) and finished in black matte. As the filter comes with a putter, it can’t fit a lens hood | 【About its Compatibility】This 82mm ND filter can only fit 82mm camera lens. Please confirm the filter thread size marked on your camera with the "Ф" (diameter) symbol before ordering. When mounted on camera, the ND filter also protects your camera lens from scratches. Protective case and cleaning cloth also included. A 86mm lens cap is required to fit on the 82mm lens filter, but is NOT included | 【Usage Notes】1. An X patterned glare or ghosting may appear when light is reduced to ND256; 2. Actual ND effects may differ at the Min and Max marks as well as in different environments; 3. For long exposure, please purchase ND1000 or ND2000 filters
