【Variable ND & CPL Filter】After adjusting the ND filter and then rotating the frame, you can realize the functions of the ND filter and the CPL filter simultaneously. This 2 in 1 filter kit allows you to shoot under bright lighting conditions to capture motion blur images. It reduces reflections and glare from shiny objects like water or glass. The variable neutral density filter reduces 1–5 stops of light
【No Dark Cross Shadow】To solve the well known vignetting issue with variable ND filters when used on wide angle lenses, the NEEWER filter set uses self locking technology to ensure that there will be no dark cross shadow or vignetting when shooting with wide angle lens
【HD Optical Glass with Multiple Resistant Coatings】 With high quality HD optical glass and 30 layers of nano coatings on the both side of the filters, the reflectivity can reach less than 0.1% to reduce flare and ghosting. Protect the filter from water, oil, dust, and scratches
【Aircraft Grade Aluminum Alloy Frame】 Made of CNC machined aluminum alloy, the non slip texture of the frame makes it easy to install and remove the filter. Laser etched marks can be precisely controlled from the minimum (ND2) to the maximum (ND32) of light reduction. Featuring ultra slim design, the front diameter is larger than the back diameter of this filter. For this 67mm ND filter, the lens cap/hood should be 72mm
【Compatibility】 Compatible with all lenses with a 67mm thread size. Please confirm your lens thread size before purchasing. The thread size is marked on the front or side of your lens, next to a "Ф" (diameter) symbol
