Moment Variable ND Filter - 67mm - 2-5 Stop

Variable ND stands for 'Neutral Density'. It means the filter reduces the amount of light entering the lens, allowing you to use slower shutter speeds or wider apertures in bright conditions. 'Variable' means you can adjust the amount of light reduction within a specified range (2-5 stops in this case), unlike fixed ND filters.

Cross-polarization is an optical effect that can create an undesirable 'X' pattern or darkening across the image, especially with variable ND filters. 'Zero Cross Polarization' means the filter is engineered to minimize or eliminate this effect, providing a cleaner image throughout its adjustable range.

The number of stops indicates how much light the filter reduces. A 2-5 stop filter reduces light by a factor of 4 to 32, suitable for moderate to bright conditions. A 6-9 stop filter reduces light by a factor of 64 to 512, designed for extremely bright conditions where maximum light reduction is needed.

No, this specific filter is designed for lenses with a 67mm filter thread. For other lens sizes, you would need a Moment Variable ND filter with the corresponding thread size (e.g., 62mm, 72mm, 77mm, 82mm).

Use a soft, lint-free microfiber cloth. For tougher smudges, a dedicated lens cleaning solution can be applied sparingly to the cloth, not directly to the lens. Avoid using paper towels or abrasive materials.

The Moment Variable ND Filter uses high-quality Schott B270 Pro Cinema Glass, which is designed for excellent color accuracy and minimal color cast. While some very slight shift might be imperceptible at the extreme ends of the range, it's engineered to be neutral.

Hard stops are physical points in the filter's rotation that indicate the minimum (2 stops) and maximum (5 stops) of its effective range. They help you quickly adjust to precise settings without needing to meticulously check markings and prevent accidentally over-rotating the filter.

This can occur at the extreme ends of the filter's range or with very wide-angle lenses. Try adjusting the filter to a slightly lower or higher stop value. Ensure you are within the recommended 2-5 stop range and avoid extreme settings. Check for any stacking of filters that might be exacerbating the issue.

Ensure the filter is screwed on straight and not cross-threaded. Check for any debris on the lens threads or filter ring. If the issue persists, the ring might require gentle cleaning. Avoid forcing the rotation.

Verify that the filter is set to the desired stop range (2-5 stops). Ensure your camera's exposure settings (aperture, shutter speed, ISO) are appropriate for the scene after applying the filter. The filter reduces light; it does not add it.
