Adopt professional optical glass, precision grinding treatment, high -definition sharpness, high -definition imaging, to meet the needs of professional photographers 6. Material: aluminum alloy, optical glass 7. Applicable models: suitable for DJI Mini 3 Pro 8. Size: 21.5x17.2x3.7mm 9. Net weight: UV: 1.5G, CPL: 2G, ND-PL: 2G x 4, ND: 1.5g x 4 UV: 1. Hardly coating process, filtering harmful light, effectively protecting lens and sensors 2. Under the vast environment such as mountains, vision, high altitude, effectively reduce the blue effect of the picture 3. High light transmission rate, without damage to the sharpness of the picture CPL: 1. Eliminate harmful non -metal reflex light, increase color concentration, make the picture clearer and more transparent 2. Applicable to deepening the contrast of blue sky and white clouds, or eliminating underwater, backlight and other shooting scenes 3. Rotary adjustment ring, adjust to the suitable effect of eliminating reflection 4. Eliminate polarizing light, improve the sharpness and expression of the picture ND set: 1. ND filter is also known as light reduction mirror, or medium gray dense mirror 2. The main effect is that when the light is too bright, the camera can choose the correct exposure value by reducing the amount of light input to avoid excessive exposure 3. It can resist the scattered light in large quantities, which can improve the color saturation of the picture, make the picture more transparent and gorgeous 4. Using the light reduction mirror can also shoot some special effects at a slow shutter sp
