Product Information
Full details
The Moment CineBloom Variable ND Filter (2-5 Stop, 10% Diffusion) is designed for filmmakers and photographers who want to achieve a cinematic, dreamy aesthetic while maintaining professional-grade exposure control. By combining a 10% diffusion filter with a 2-5 stop variable neutral density adjustment, this tool softens harsh highlights and digital sharpness for a more natural look. While it offers unparalleled convenience for run-and-gun shooting, users should be aware that combining diffusion with ND filtration can occasionally lead to subtle color shifts or vignette effects when used with extreme wide-angle lenses.

FAQs
Will this filter fit all lenses?
This filter is designed for lenses with specific thread sizes. Check your lens barrel or manual for the symbol followed by a number (e.g., 77mm) to ensure compatibility.
Can I use a lens hood with this filter?
Yes, provided the lens hood is a screw-in type that attaches to the front threads of the filter, or if your lens uses a dedicated hood that does not conflict with the filter diameter.
Does the 10% diffusion affect autofocus?
No, the diffusion layer is subtle and does not interfere with modern camera autofocus systems.
Is this filter weather-sealed?
The filter features hydrophobic and oleophobic coatings that repel water and oil, making it highly resistant to harsh environments, though it is not technically waterproof.
Why are there hard stops on the filter?
Hard stops prevent you from rotating the filter past its intended range, which effectively eliminates the unsightly dark 'X' pattern caused by over-polarized light.
Can I use this for long-exposure photography?
The 2-5 stop range is best suited for video exposure control. For long-exposure photography during bright daylight, you may require a stronger fixed ND filter (e.g., 10-stop).
Troubleshooting
Visible vignetting on corners of the image
Vignetting usually occurs if you are using an ultra-wide lens. Try zooming in slightly or using a larger diameter filter with a step-up ring.
Difficulty rotating the filter ring
Ensure the filter is not screwed onto the lens too tightly. Check that no debris is lodged in the rotating mechanism.
Flare or ghosting artifacts
Ensure the filter surface is clean. Even with anti-glare coatings, shooting directly into the sun can cause internal reflections; adjust your framing or use a lens hood.
Pros and Cons
Pros
- Reduces harsh digital sharpness for a more organic, cinematic image
- Eliminates the need to carry and swap multiple fixed ND filters
- Hard stops prevent cross-polarization artifacts
- Easy to clean thanks to hydrophobic and oleophobic coatings
- Maintains sharp image quality across the frame
Cons
- Not suitable for ultra-wide angle lenses due to potential vignetting
- Adding two filter types in one housing increases overall thickness
- Expensive compared to standard single-function filters
Setup, Compatibility & Care
To install, simply screw the filter onto the front threads of your lens, ensuring a snug but not overtightened fit. Because of the dual-element design, ensure your lens cap size is compatible with the filter's front diameter if you intend to use a cap while the filter is mounted. When storing, keep the filter in its protective case to prevent scratching the Schott glass. If the surface collects dust or oils, use a dedicated microfiber lens cloth. For stubborn smudges, apply a small amount of optical lens cleaning solution to the cloth before gently wiping the glass in a circular motion.
