CineBloom Diffusion Filters, 37mm / 10%
$44
Our CineBloom Diffusion Filter gives your digital camera the look and feel of film. Its unique character softens harsh digital detail, blooms highlights, and wraps your image in a dreamy, cinematic glow — all without sacrificing sharpness or color accuracy. CineBloom is our custom diffusion recipe: a specific particle blend that’s sandwiched between two layers of HD optical glass and protected by a water-, grease-, and dirt-resistant coating. Powered by our Moment Filter Formula and available in 5%, 10%, and 20% strengths, it delivers that unmistakable filmic softness — straight out of camera. Finished with a lightweight aluminum frame and knurled grip, it screws on easily and stacks cleanly under ND or VND filters. No plastic, no gimmicks — just a timeless look you can rely on.
Our Review
CineBloom Diffusion Filter, 37mm / 10% — the compact filter for your mobile lens travel kit
The gist: Sized for smaller lens threads, this filter adds the same cinematic glow to your phone-lens setup without adding bulk to a minimalist travel kit.
- Same optical formula, smaller size: Built from Japanese optical glass in an aerospace-grade aluminum frame, matching the larger CineBloom filters’ construction at a compact 37mm.
- Diffuses light directly in-camera: Softens harsh highlights and blooms light sources like sunsets or string lights — no editing app required to get the look.
- 10% strength: The middle option between the subtler 5% and the heavier 20% filter, balancing visible glow with retained sharpness.
- Fits compact mobile setups: The 37mm thread matches smaller Moment mobile lenses, keeping your whole kit pocket-sized.
Fstoppers’ hands-on review of the CineBloom line found the filters preserve image sharpness while adding a subtle, classic-cinema glow — a rare balance in a filter this affordable.
Best for: minimalist travelers shooting on a phone-and-lens-kit setup who still want an in-camera film look. Skip it if: your main lens uses a larger thread size — check compatibility first. Runs ~$44 — check the current price before buying.
