K&F Concept 49mm Variable ND Filter+CPL Circular Polarising Polarizer Filter 2 in 1 Function Graduated Fader Neutral Density MRC 18 Layer ND2 ND4 ND8 ND16 to ND32 No Spox X Issue

Variable ND & CPL Filter: After adjusting the ND filter and then rotating the frame, you can realise the functions of ND filter and 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 such as water and glass. The variable neutral density filter reduces light by 1-5 f-stops. No dark cross shadow: To solve the well-known vignetting problem of variable ND filters when used with wide-angle lenses, the filter uses self-locking technology to ensure that there is no dark cross shadow or vignetting when shooting with a wide-angle lens. HD Optical Glass with Multiple Resistant Coatings: With high quality HD optical glass and 28 layers of nano coatings on both sides 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 Aluminium Alloy Frame : Made of CNC machined aluminium alloy, the non-slip texture of the frame makes it easy to install and remove the filter. Laser etched markings can be precisely controlled from the minimum (ND2) to the maximum (ND32) of light reduction. With its ultra-slim design, the front diameter of this filter is larger than the rear diameter. Compatibility: Compatible with all lenses with 49mm thread size. Please confirm your lens thread size before purchase. The thread size is marked on the front or side of your lens, next to a "Ф" (diameter) symbol.
