1、Exquisite Workmanship: Aviation aluminum alloy frame, CNC precise machining, anodized coloring process. Excellent lens grinding process, good physical and chemical properties make the image clearer and make your work more professional. 2、Adjustable Angle: CPL and ND, PL are adjustable filters, and the golden frame can be rotated as needed to achieve satisfactory polarization requirements when shooting. 3、Coating and Magnetic Installation: Multi layer coating, high transparency and high brightness, restore true color, and take pictures more wonderfully. Magnetic installation, firm fit, gently close, you can firmly adsorb. 4、Frame Design and Reserved Holes: The frame is ingeniously designed, so there is no need to worry about the filter scratching or damaging the original lens. The radio and indicator holes are reserved, which will not affect the radio and indicator display. 5、CPL Filter: CPL adjustable polarizer is mainly used to eliminate harmful non metal reflection light, increase the color concentration to deepen the sky blue, highlight the white clouds, make the picture more transparent, and improve the clarity and expressiveness of the picture. It is also often used to shoot scenes behind glass, clear and transparent water and underwater objects. 6、ND PL Filter: Adjustable ND PL light reducing polarizing filter, which combines the advantages of ND light reducing and CPL polarizing lenses, breaks through the limitations of traditional filters, and at the same time meets the photographer's two requirements for extending exposure time and eliminating harmful polarized light. Shooting tool. 7、ND Filter Function: The main function of ND filter is to reduce the amount of incoming light when the light is too bright, so that the camera can choose the correct exposure value and avoid overexposure. It can also "block" a large amount of scattered light, which can improve the color saturation of the picture and make the picture more transparent and bright. Using the ND filter can also use a slower shutter speed to shoot some special effects, such as foggy water, light trails at night, etc. When shooting videos under the hot sun, you can reduce the shutter speed and gate speed through the ND filter, so that the video picture has proper motion blur and looks more comfortable. 8、MCUV Filter: When the MCUV filter is used for shooting in broad environments such as mountains, distant scenes, and high altitudes, due to the high color temperature and the increased proportion of blue wavelength and ultraviolet, the captured image will be bluish, and the yellow red exposure will be insufficient. Using the MCUV filter can effectively reduce the exposure. The blue tone and blue gray tone caused by ultraviolet rays increase the transmittance and make the picture quality clearer. 6 x Filter1 x Wipe2 x Storage Box1 x Label Sticker Item Type: Filter Combo for Action 2Material: Aluminum Alloy, Optical GlassProduct Size: Approx. 40x40mm / 1.6x 1.6inApplicable Models: Suitable for Action 2Color: As Pictures ShownWeight: Approx. 177g / 6.2oz
