CineBloom Diffusion Filters - Open Box, 10% / 52mm
Our CineBloom Diffusion Filters are the secret sauce for capturing dreamy, film-like footage. Escape the clinical, ultra-sharp look of digital with this specialty glass. Available in densities of 5%, 10%, and 20%, they not only catch and bloom light but soften hard edges and provide a smoothing effect on skin tones, making wrinkles less noticeable. The glass itself is made by fusing a microlayer of NanoBlack particulates between two layers of top-grade Japanese filter glass, allowing us to maintain full image quality. The ring of the filter is precision machined from aerospace-grade metal and designed to be thin enough to stack underneath another filter without compromising the field of view. This means you can use an ND or VND on top of it for shooting cinematic frame rates and capturing motion blur. Take your footage to new cinematic heights with CineBloom from Moment.

Moment CineBloom Diffusion Filter — Instant Film Glow for Travel Filmmakers
The gist: A stackable glass diffusion filter that removes the clinical sharpness of modern sensors and replaces it with the soft bloom, lifted blacks, and dreamy highlight glow of vintage film — in the field, with no post-processing needed.
- Three density options (5%, 10%, 20%): 5% adds a barely-there softening for subtle character; 10% is the versatile all-rounder; 20% creates an editorial-magazine effect ideal for portraits and golden-hour travel footage.
- Japanese optical glass + aerospace aluminum: Premium glass construction maintains image sharpness while adding the diffusion effect — no degradation in resolution or color accuracy.
- Stackable thin ring: The precision-machined frame is thin enough to stack with an ND or VND filter on top for cinematic slow-motion while shooting outdoors.
- 12-month warranty, open-box pricing: Open Box units are blemish-free with all original accessories — the ideal entry point into Moment’s filter system at a lower cost.
Fstoppers called the CineBloom “much more affordable than filters that have been in the industry for some time,” noting it effectively mimics the bloom and highlight rolloff of vintage film glass on modern mirrorless cameras.
Best for: Travel filmmakers and photographers who want cinematic, film-like character without relying on heavy post-production grading. Skip it if: You shoot primarily in low light — diffusion filters amplify existing lens flare and may soften critical details in dark scenes. Runs ~$43 — check the current price before buying.
