Moment Cinebloom Diffusion Filter (20%, 77mm) - Cinematic Glow

In this review the Moment Cinebloom Diffusion Filter (20%, 77mm) is assessed for photographers and filmmakers seeking a soft, cinematic look without sacrificing clarity. The bottom line: this filter is best for creatives who want a pronounced bloom and gentle reduction in digital sharpness while keeping accurate colors, because it uses Schott B270 optical glass to deliver diffusion with minimal image degradation. It pairs well with DSLRs, mirrorless and cinema lenses that accept standard threads and stacks cleanly with exposure filters.

Key Features

• Dreamy, cinematic look: The 20% diffusion strength softens hard edges and adds a natural glow to highlights for a film-like aesthetic without making images mushy.
• Professional-grade glass: Built from Schott B270 optical glass to preserve clarity and avoid color shift, so images retain accurate tones.
• Broad lens compatibility: Fits lenses with thread sizes between 37mm and 82mm, making it usable on a wide range of DSLR, mirrorless and cinema glass.
• Stackable design: Can be stacked with ND and VND filters to maintain exposure control while keeping the soft diffusion effect.
• Multiple strengths available: Offered in 5%, 10%, and 20% so users can choose from subtle softening to a more vintage-inspired bloom.
• Lifetime guarantee: Backed by Moment's lifetime guarantee for long-term professional-quality performance and peace of mind.

Who It's For

The Cinebloom 20% is aimed at photographers and filmmakers who want a noticeable but controlled diffusion - wedding shooters, indie filmmakers and portrait photographers will appreciate the way highlights bloom and skin textures soften while retaining detail. Those shooting both photo and video will benefit from consistent color and clarity thanks to the Schott glass.

It is less appropriate for users who require razor-sharp, clinical detail or those who need only a barely-there effect; in those cases the 5% or 10% versions or no filter would be a better fit. Also, if your lenses use nonstandard thread adapters outside the 37mm-82mm range you should verify fit before buying.
