Product Information
Full details
This Moment 67mm CineBloom Variable ND Filter is designed for filmmakers and videographers seeking to achieve a distinct cinematic look. Its primary benefit is the unique CineBloom effect, which softens highlights and motion while the integrated 2-5 stop Variable ND controls exposure. A potential caveat is the 20% light transmission, which might require adjustments in very low light scenarios. It combines two filters into one, reducing the need for stacking and simplifying your setup.

FAQs
What does 'CineBloom' effect mean?
The CineBloom effect refers to the filter's ability to soften bright highlights, reduce digital sharpness, and smooth motion, giving footage a dreamy, cinematic quality often seen in film.
What is the benefit of a 'Variable' ND filter?
A variable ND filter allows you to continuously adjust the amount of light reduction (in this case, 2-5 stops) by rotating a ring, giving you precise control over exposure and motion blur without needing to swap out multiple filters.
Can I stack other filters on top of this one?
While technically possible, it is not recommended as it can lead to vignetting (darkening at the edges of the frame) and exacerbate X-patterns. This filter is designed to be used on its own.
What is the 20% light transmission mean for my footage?
A 20% light transmission means that roughly 20% of the light entering your lens will pass through to the sensor. This results in a significant darkening of the image (approximately 2.3 stops of ND effect from transmission alone), allowing for creative control in brighter conditions.
How do I clean the filter's coatings?
Use a soft microfiber lens cloth and a dedicated lens cleaning solution. Gently wipe in a circular motion from the center outwards. Avoid using abrasive materials or harsh chemicals.
What is the advantage of having two filters in one?
Combining the CineBloom effect and the Variable ND into a single unit simplifies your gear, reduces the weight and bulk of carrying multiple filters, and minimizes the risk of light leaks or vignetting that can occur when stacking filters.
Will this filter work with my camera's autofocus?
Yes, this filter is designed to not interfere with your camera's autofocus system. The neutral density it provides affects light evenly across the sensor.
Troubleshooting
X-Pattern visible in the image
This is common with variable ND filters at extreme settings. Rotate the outer ring to find a point where the X-pattern disappears. Try using a different ND stop if possible or a fixed ND filter.
Color cast or shift in footage
Ensure the filter is set within its optimal range (avoiding extreme ends). High-quality filters like this minimize shifts, but some subtle color change can occur. Adjust white balance in post-production if necessary.
Filter is difficult to screw on/off
Ensure you are using the correct size filter and that the lens threads are clean and free of debris. Do not force the filter; if it binds, remove it and try again gently.
Bloom effect is too strong or not noticeable
The CineBloom effect is subtle and designed to enhance, not overpower. Its visibility depends on the lighting conditions. Experiment with different lighting and shooting angles to see its full effect.
Pros and Cons
Pros
- Creates a distinct cinematic bloom effect.
- Combines ND and bloom filter into one unit, saving space and hassle.
- Provides precise control over exposure with a variable ND.
- High-quality optical glass for sharp, color-accurate images.
- Durable coatings resist fingerprints, water, and glare.
Cons
- 20% light transmission may be too dark for some very low-light situations.
- Variable ND can introduce slight color shifts at extreme ends.
- Requires careful handling to maintain coatings.
- Only available in 67mm thread size (without adapters).
Setup, Compatibility & Care
Setup: Screw the Moment 67mm CineBloom Variable ND Filter onto the front of your 67mm threaded lens. Ensure it is securely attached but do not overtighten. To adjust the ND level, rotate the outer ring of the filter. The hard stops indicate the maximum and minimum ND settings.
Compatibility: This filter is designed for lenses with a 67mm front filter thread. For lenses with different thread sizes, you will need a compatible step-up or step-down ring.
Care: Clean the filter regularly using a lens cleaning cloth and a lens cleaning solution. Avoid touching the glass directly. The oleophobic and hydrophobic coatings help repel smudges, but regular cleaning with a microfiber cloth is recommended. Store the filter in its protective case when not in use to prevent scratches and damage.
