K&F Concept 77mm Variable ND Filter ND3-ND1000 (1.5-10 Stops), 28-Layer Coatings HD Optical Glass Adjustable Neutral Density Filter for Camera Lens(Nano-X Series)

【Top HD Optical Glass】This variable ND3-1000 filter is made of AGC optical glass, a total of 28 layers of coatings, which effectively reduces reflections and glare from the filter itself, ensuring high quality images and no blurring. 【Pusher Design】This filter frame is designed with a pusher to help you adjust the stops accurately, for video shooting users can automatically adjust the stop via auxiliary tools, each stop from ND3 to ND1000 is marked on the frame for easy 360 degree rotation to adjust the stops and multi-scene applications. 【Hydrophobic & Scratch Resistant】The K&F Concept ND filter has a multi-layer hydrophobic, oil and scratch resistant coating on both glass sides, protecting the ND filter in all aspects for adventurous use. 【No Vignetting】For filters with ultra-wide angle design, the ultra-thin bezel is only 7.4mm and supports 16mm telephoto and wide angle lenses with no vignetting. Due to the difference in lens type and focal length, this filter may experience dark "X" cross, which is not a quality issue and can disappear by rotating the filter. 【Choosing the right size】Please check the lens thread size of your camera before ordering. Your camera's lens thread size will be marked somewhere on the barrel, or printed under your lens cap. This number is always preceded by a "ø" (diameter) symbol.
