Ulanzi MF01 1/4 Black Mist Filter Magnetic Filter Adapter Ring

The Ulanzi MF01 1/4 Black Mist Magnetic Filter is designed for photographers and videographers seeking a cinematic, soft-focus look with fast, effortless operation. Featuring a 1/4 Black Mist effect, magnetic mounting system, and high-quality optical glass, it gently softens highlights and skin tones while reducing glare, perfect for portraits, filmmaking, and atmospheric visuals.

This professional-grade diffusion filter enhances cinematic aesthetics in both photo and video shooting. Its 1/4 Black Mist effect subtly diffuses highlights, softens harsh light, and smooths skin textures while preserving overall image detail, making it especially effective for portrait photography, wedding shoots, and cinematic video production.

Constructed from premium optical glass and housed in a durable, ultra-thin aluminum alloy frame, the filter prevents vignetting even when used with wide-angle lenses. The double-sided protective coating repels water, oil, and fingerprints, ensuring easy cleaning and long-lasting clarity. The standout magnetic design allows for instant installation and removal, enabling quick filter changes during fast-paced shoots. Compatible with lenses using 67mm, 72mm, or 77mm adapter rings (sold separately), the MF01 offers excellent flexibility for creators using multiple lens setups.
