【Black Diffusion Camera Lens Filter】 This 1/4 diffusion filter adds a soft, cinematic glow to your footage by reducing harsh highlights and glare. It smooths skin tones for a more flattering look, making it perfect for portrait photography, video shooting, and vlogging. 【Soft, Even Light Effect】 Creates a dreamy and cinematic atmosphere with gentle light diffusion, helping you achieve a professional film-like aesthetic. 【Durable Multi-Layer Nano Coating】 Features multiple nano coatings on both sides that repel water, resist scratches, and prevent fingerprints and smudges. It also minimizes unwanted reflections from both the filter and surrounding surfaces. 【Ultra-Slim, Non-Slip Frame】 The ultra-slim design prevents vignetting on wide-angle and telephoto lenses. CNC-machined trapezoidal patterns on the frame provide a secure grip for easy installation and removal. 【How to Choose the Right Size】 This filter is compatible with all 52mm camera lenses. Please check your lens for the correct filter thread size, usually marked on the front or side of the lens with a “ø” symbol (e.g., ø52mm).
