Main features for the JetMag Pro Black Magic Diffusion 1/4 filter
Controlled Highlight Bloom for Cinematic Atmosphere
Unlike traditional mist filters that can overly diffuse highlights, the Black Magic Diffusion JetMag Pro delivers a cleaner, more refined bloom. Highlights are softened with precision, maintaining clarity while introducing a cinematic glow that elevates your visuals.
- Smooth and Flattering Skin Tones
This filter is especially effective for interviews, portraits, and close-ups, where it gently smooths skin textures and reduces imperfections while retaining critical sharpness in eyes, hair, and facial details. The result is professional, flattering imagery straight out of camera.

- Retained Contrast and Accurate Colour
Engineered to complement modern high-resolution sensors, the Black Magic Diffusion preserves natural color saturation and avoids heavy contrast reduction. It softens harsh edges while keeping images clean, balanced, and true-to-life—a look difficult to achieve with post-processing alone.

- A Dreamy, Vintage Film Look
The filter introduces subtle halation and a nostalgic warmth that instantly recalls the aesthetics of film stock. This dreamy, vintage-inspired character adds emotional weight and artistic depth to narratives, music videos, weddings, and commercial work.

Black Magic Diffusion vs. Black Mist
Built into the NiSi JetMag Pro system, the filter snaps on and off in seconds, perfect for fast-paced shoots or when working with multiple filters. The patented JetMag locking mechanism ensures the filter stays securely in place, even when stacking, working handheld, or operating in windy conditions.


Black Mist filters create a more pronounced and widespread glow with a stronger reduction in contrast, producing a softer effect across the entire scene.
The Black Magic Diffusion filter, on the other hand, delivers a subtler diffusion limited to the highlights, while also smoothing skin tones. It preserves detail definition more effectively, making it ideal when aiming for a gently softened look without overly diffusing fine details.
These filters cannot be used on their own, but you will need to purchase the JetMag Pro Adapter Ring in order to use them on your lens.
We also recommend getting a JetMag Pro Front and Back Lens Caps to protect your filter.
Perfect to be used in combination with the JetMag Pro FS ND, JetMag Pro True Color CPL , JetMag Pro Night Filters and the JetMag Pro UV filters, also compatible with the JetMag Pro Back Lens Cap.
