The Tiffen 105C Black Pro-Mist 1/4 is a professional-grade 105mm circular glass filter designed to create a subtle, cinematic diffusion effect by softening excess sharpness and reducing contrast in video and photography. Utilizing Tiffen's proprietary ColorCore technology, the filter is constructed by laminating the filter substrate between two pieces of precision optical glass, which are then ground flat to a tolerance of 1/10,000th of an inch for exceptional clarity and consistency. The Grade 1/4 density represents a balanced diffusion strength—more pronounced than the 1/8 but less than the 1/2—that smooths facial wrinkles and blemishes while generating a controlled, pearlescent halation around highlights without significant loss of image detail.

Engineered for professional cinematography, fashion, and beauty applications, the Black Pro-Mist 1/4 reduces highlight values while slightly lowering overall contrast to create a soft, pastel-like quality of light that mimics the aesthetic of film. The filter features a coarse thread pitch designed specifically for large-diameter cine-style lenses, helping to prevent cross-threading during attachment. The black anodized aluminum ring remains durable yet lightweight, with 105mm front accessory threads allowing for stacking additional filters such as variable NDs when expanded creative control is needed. The included soft pouch provides secure storage and protection when the filter is not in use.
