Urth 49mm ND2-32 Variable ND Lens Filter Plus+ - 1-5 Stop

ND2-32 refers to the range of light reduction. ND2 blocks 1 stop of light, and ND32 blocks 5 stops of light. The filter is variable, allowing you to choose any value between these two extremes.

Use a clean, dry microfiber lens cloth to wipe the surface. For tougher smudges, lightly dampen the cloth with a dedicated lens cleaning solution and wipe gently. Avoid using abrasive materials.

The 'X-effect' is a cross-polarization artifact that can appear as an 'X' shape on images, especially at higher densities of variable ND filters. The Urth filter features a locking rim to help prevent over-rotation and minimize this effect, but it can still occur at the extreme ends of the filter's range.

This specific filter is 49mm. Urth offers this variable ND filter in a range of other sizes (e.g., 39mm, 58mm, 77mm) to fit different lenses. You may need step-up rings if your lens has a different thread size.

Urth provides a lifetime warranty on this filter, indicating confidence in its quality and durability.

Yes, the variable nature of this ND filter makes it very useful for video recording, allowing you to maintain a consistent shutter speed (typically double your frame rate) even in changing light conditions, while adjusting aperture for depth of field.

This 'X-effect' is common with variable ND filters at extreme ranges. Try rotating the filter rim to a setting slightly away from the maximum or minimum. The locking rim helps prevent this, but it can still occur.

This can sometimes happen with variable ND filters. Ensure the filter is set within its optimal range. Minor color casts can often be corrected in post-processing software.

Check that you are using the correct filter size (49mm) and that the lens threads are clean and undamaged. Do not force the filter; if it doesn't screw on smoothly, re-align and try again gently.

While the ultra-slim rim is designed to prevent this, extreme wide-angle lenses might still experience slight vignetting at certain zoom or focus levels. Try adjusting your focal length or ensure the filter is properly seated.
