Moment Cinebloom Diffusion Filter (20%, 37mm) - Cinematic Glow

In this review the Moment Cinebloom Diffusion Filter (20%, 37mm) proves itself as a purpose-built tool for creators who want a film-like softness without sacrificing image clarity. The biggest reason to buy is that it delivers a pronounced, vintage-inspired bloom while retaining accurate color and sharpness thanks to its Schott B270 optical glass, so photographers and videographers who want a controlled, cinematic glow will appreciate the results.

Key Features

• Dreamy, cinematic look: Softens hard edges and adds a natural glow to highlights to create a film aesthetic that reads well for both stills and motion.
• Professional-grade glass: Constructed from Schott B270 optical glass to minimize color shift and avoid image degradation even with strong diffusion.
• Compact fit range: Sized for a 37mm thread while designed to work across lenses with standard threads up to 82mm via appropriate mounts, making it versatile for DSLRs, mirrorless, and cinema lenses.
• Stackable design: Can be stacked with ND and VND filters to keep exposure control while adding the soft diffusion effect during shoots.
• Multiple strengths: The 20% strength delivers a bold glow, with the same glass construction available in 5% and 10% for more subtle looks.
• Lifetime guarantee: Backed by Moment's lifetime guarantee, giving confidence in long-term professional use.

Who It's For

The Cinebloom 20% is aimed at photographers and filmmakers who want a distinct, vintage-style bloom in their images and footage without introducing unwanted color casts; it suits portrait, wedding, and narrative work where highlights benefit from a soft glow. It also works well for mobile shooters who adapt lenses and filter mounts around the recommended 67mm or use step-up rings for 37mm threading.

Those seeking zero softening or the absolute maximum micro-detail will want to look elsewhere or consider the 5% or 10% versions instead, but anyone who wants a clear, controlled diffusion effect that still preserves overall image integrity will find this strength effective.

Pros & Cons
