Moment Cinebloom Diffusion Filter (20%, 62mm) - Cinematic Soft Glow

In this review the Moment Cinebloom Diffusion Filter (20%, 62mm) is evaluated for photographers and filmmakers seeking a true film-like glow without sacrificing clarity. The bottom line: it delivers a pronounced, vintage-inspired bloom that softens harsh edges and reduces digital sharpness while preserving color accuracy thanks to professional-grade Schott B270 glass. For creators who want a dreamy, cinematic look in both stills and video, this filter is a straightforward tool that produces consistent, usable results with lenses that accept standard thread sizes.

Key Features

• Dreamy, Cinematic Look: Produces a natural glow around highlights to emulate film softness and reduce digital crispness for a more organic aesthetic.
• Professional Optical Glass: Built from Schott B270 glass to maintain exceptional clarity and avoid color shift so images remain true to the scene.
• Wide Compatibility: Works with lenses from 37mm to 82mm thread sizes, making it suitable for DSLR, mirrorless, and cinema lenses with standard threads.
• Stackable Design: Can be combined with ND and VND filters so users can control exposure while keeping the diffusion effect intact.
• Multiple Strengths: Available in 5%, 10%, and this 20% strength to choose between subtle softening and a stronger, vintage bloom.
• Lifetime Guarantee: Backed by Moment's lifetime guarantee for long-term professional use and confidence in durability.

Who It's For

The filter suits photographers and videographers who want to soften hard edges and achieve a film-like glow without introducing color casts; it is particularly useful for portrait, cinematic B-roll, and atmospheric landscape work where highlights benefit from a controlled bloom. Mobile creators using Moment lenses and filter mounts will find the recommended 67mm size helpful, while this 62mm size fits lenses with that thread diameter.

Those who need absolutely razor-sharp clinical detail, or who rely on heavy post-production sharpening for handheld footage, may prefer to avoid strong diffusion. Also, if a user requires variable in-camera diffusion control, a dedicated diffusion adapter or softer optical solutions may be more appropriate.

Pros & Cons

Pros

• High-quality Schott B270 glass preserves color and avoids image degradation while adding soft bloom.
• Noticeable and pleasing diffusion that reduces digital sharpness without muddying detail.
• Stackable with ND/VND filters so exposure and creative effects can be managed together.
• Available strengths give creative control from subtle to bold diffusion effects.

Cons

• Strong 20% diffusion may be too pronounced for photographers who want maximum micro-contrast and edge detail.
• Users must match thread sizes carefully; 67mm is recommended for Moment mounts but this unit is 62mm, which limits direct compatibility with some accessories.
