This is a variable ND filter for the DJI Mini 4 Pro from K&F Concept, a popular camera filter brand. I mistakenly ordered it, intending to buy one for the Pocket 3, and cannot return it, so I am selling it. It has been opened, but it is new and unused. I hope you can make good use of it. Features: * 【Light Reduction Effect】K&F Concept ND32-512 provides 5-9 stops of light reduction, ideal for bright lighting conditions, and the limited variable ND filter can be adjusted according to the needs of the shooting scene. * 【Multi-Coated HD Optical Glass】This K&F Concept Mini 4 Pro filter kit is made of top AGC optical glass, which controls light without losing image clarity, helps capture vivid colors, and manages contrast. It has 28 layers of nano-coating on both sides, providing strong protection against scratches, dust, dirt, water, and oil. * 【No Impact on Gimbal】K&F Concept's ultra-lightweight technology ensures that each filter frame passes rigorous testing without adversely affecting the drone's gimbal calibration or performance, weighing only 2g/0.07oz. * 【Perfect Fit and Quick Installation】Precise back buckle design that perfectly matches the Mini 4 Pro camera lens base. Easy to disassemble and assemble, just snap it on to securely hold the camera during flight. * 【Package Contents】1 ND32-512 filter for DJI Mini 4 Pro, each filter comes with a sturdy filter case. #filter #NDfilter #lightreductionfilter #DJI #Mini4 #variable #concept
