【Variable ND2-ND32 Camera Lens Filters】 This 43mm variable camera lens filter features 5 stops of exposure brightness, from ND2, ND4, ND8, ND16 to ND32 (the numbers represent how much light enters the lens in terms of a fraction). Use this filter to gain more control over exposure and shutter speed when shooting rivers, waterfalls, light trails, etc | 【No X cross dark spot】 With markers on the frame, rotate the filter to accurately adjust ND stop with ease. When mounted on wide angle lens, no need to worry about X cross dark spot. A 46mm lens cap is required to fit on the 43mm filter | 【Multi Layer Nano Coated HD Optical Glass】 Made of premium Japanese AGC optical glass, the high definition ND filter delivers cinematic photo look without distorting image quality. The 30 layers of double sided Nano coatings, with 0.1% minimum light reflectivity, reduce flare and ghosting while protecting the filter against moisture, oil, dust, and scratches | 【Professional Build】 The aircraft grade aluminum frame makes the filter lightweight. 0.37"/9.5mm thick (including thread, 0.29"/7.4mm thick excluding thread), this ultra slim filter helps avoid vignetting. Finished in black matte and CNC precisely machined, it is durable and has zero chance of being jammed on lens | 【About its Compatibility】 This 43mm ND filter can only fit 43mm 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.
