Features: .Multi-layer Coating: adopting multi-layer nano-coating process, high transparency and high brightness, oil-proof, anti-fouling, anti-scratch, clearer shooting. .High-quality Optical Glass: high-definition grinding treatment, good physical and chemical properties, clearer imaging, to meet the professional requirements of professional photographers for light and shadow, a single filter weighs about 0.76-0.8g, uses a quick-installation structure, and does not affect the gimbal calibration . .UV Filter: UV color filter. When shooting in a wide range of environments such as mountains, distant views, and high altitudes, due to the high color temperature, the blue wavelength and the proportion of ultraviolet rays increase, the captured image will be bluish, and the yellow-red exposure will be insufficient. Can effectively reduce the occurrence of this phenomenon. .CPL Filter: CPL filter, also called circular polarizer, is mainly used to eliminate harmful non-metal reflected light, increase color density, deepen blue sky, highlight white clouds, make the picture more transparent, and improve the clarity and expressiveness of the picture . It is also often used for photographing scenery behind glass, clear and transparent water, and underwater creatures. .ND Filter: ND filter is also called light reduction lens, or medium density lens. The main effect is to reduce the amount of incoming light when the light is too bright so that the camera can choose the correct exposure value to avoid overexposure. It can also "block" a large amount of scattered light, which can increase the color saturation of the picture and make the picture more transparent and beautiful. Using a dimmer lens can also shoot some special effects with a slower shutter speed, such as misty water, light tracks at night, and so on. When shooting a video in the hot sun, you can reduce the shutter speed through the dimmer to make the video picture have appropriate motion blur and look more comfortable.
