This effect can make the shooting image visually stunning without the need for post production touch ups.2. COATING: Halo filters are coated with coating technology, which contains an ultra hard metal compound component that prevents the filter from being scratched by hard objects such as grit, and guarantees that the filter's optical performance will be effective for a long time. This halo filter creates a diffuse distortion effect around the focus point, creating a fantastic blurring effect and increasing the impact of light.3. MULTIPLE APPLICATION SCENARIOS: The halo filter is suitable for a variety of scenarios such as video shooting, portrait shooting, still life scenery, etc., and can make your photos or videos full of storytelling.4. WATERPROOF AND EASY TO CLEAN: The surface of the halo filter is delicate and smooth, with waterproof performance. This not only facilitates cleaning, but also increases the durability of the lens. The halo filter is CNC precisely molded and processed with a non slip texture, making it easier for photographers to use.5. GOOD RESISTANCE TO GREASE AND STAIN: Halo filters have an anti grease and stain coating layer, which makes the surface of the lenses glossy and resistant to stains. This effectively protects the lens so that it can still provide clear images in harsh environments.Specification:Item Type: Halo Special Effects FilterMaterial: Optical GlassNumber Of Coating Layers: Double Sided Multi Layer CoatingPackage List:1 xHalo Special Effect Filter1 x Storage Bag1 x Cleaning Cloth
