Black Magic Diffusion 1/4, purchased through personal import. Opened once for testing, like new. Parallel import, cheaper than buying in Japan (19,800 yen). Softens digital edges for natural, gentle depiction. Black Magic Diffusion 1/4 is a soft filter that combines precision nano-lenslets (a structure with hundreds of extremely small convex lenses arranged) and black mist diffusion to soften highlights without losing detail, giving a sophisticated cinematic glow. It's ideal for portraits, interviews, and beauty shoots, smoothing skin texture while keeping eyes and hair sharp, creating attractive skin tones. It maintains accurate saturation and achieves emotionally rich storytelling and vintage film-like nuances with subtle halation and nostalgic warmth. Using cinema-grade optical glass with double-sided nano anti-reflective coating for waterproof and oil-proof protection, it enables high-quality video expression in all genres, from portraits, dramas, weddings, documentaries, to music videos.
