Urth 82mm ND64-1000 Variable ND Lens Filter Plus+

A variable ND filter allows you to continuously adjust the amount of light reduction, giving you precise control over exposure without having to swap out multiple filters. This is ideal for situations with changing light conditions or when you need fine-tuned adjustments for creative effects.

The filter will fit any lens with an 82mm front filter thread. Look for a marking on your lens barrel, often near the front, that indicates the filter size (e.g., 'Ø 82mm').

Yes, the filter features a double-threaded design, allowing you to stack other filters, such as a polarizer or a UV filter, on top of it.

'6-10 Stop' refers to the range of light reduction the filter can provide. A 6-stop reduction means the light entering the lens is reduced by 2^6 (64) times, and a 10-stop reduction reduces it by 2^10 (1024) times. This allows for much longer exposures or wider apertures in bright light.

The 20-layer nano-coating provides a durable, hydrophobic, and oleophobic surface. This makes the filter easier to clean, more resistant to water spots, oil smudges, and scratches, ensuring clearer images.

The 'X' effect, also known as cross-polarization or vignetting, can appear as an 'X' shaped darkening or color shift across the image, usually at the maximum density settings of a variable ND filter. To avoid it, do not push the filter to its absolute extreme settings. Rotate the adjustment ring slightly back from the maximum setting to ensure an even light reduction.

This can occur at the extreme ends of the variable ND range. Rotate the filter slightly to find a clearer setting, or consider using a fixed ND filter for the most critical situations.

Ensure you are using the correct filter size (82mm) for your lens. Check for any debris on the lens threads or filter threads. Do not force the filter; try re-aligning it and screwing it on gently.

Ensure the filter is clean and free of smudges or dust. Verify that the filter is securely attached and not cross-threaded. If the issue persists, the softening might be at the maximum density setting; try reducing the ND level.
