The Urth 82mm Variable ND Lens Filter Plus+ is for photographers and videographers seeking enhanced control over light in dynamic shooting conditions. Its primary benefit is allowing precise adjustment of light reduction from 3 to 7 stops, enabling creative effects like shallow depth of field or smooth motion blur without overexposure. A potential caveat is the learning curve associated with achieving perfect neutrality at extreme stops. This filter is crafted from 20 layers of nano-coated German SCHOTT glass for color neutrality and sharpness, featuring a min-max locking mechanism and f-number markings for accurate adjustments.

Variable ND means the filter's density can be adjusted continuously within a specified range, allowing you to change the amount of light blocked without swapping out multiple filters.
ND8 refers to a reduction of 3 stops of light (the '8' is 2 to the power of 3), and ND128 refers to a reduction of 7 stops of light (the '128' is 2 to the power of 7). This filter covers that range.
This specific filter is 82mm. For other lens sizes, you would need to purchase a corresponding Urth filter in that size (e.g., 77mm, 72mm) or use a step-up ring.
The Urth Plus+ filters are designed with 20 layers of nano-coating on German SCHOTT glass to maintain excellent color neutrality. However, extreme settings on any variable ND filter can sometimes introduce a slight color shift.
Use a soft lens cloth or a microfiber cloth. For stubborn smudges, lightly dampen the cloth with lens cleaning solution. Always wipe gently from the center outwards.
Variable ND filters are generally not recommended for astrophotography, as they can introduce unwanted artifacts and color casts, especially at their minimum or maximum settings. Prime ND filters are preferred for such applications.
The locking mechanism prevents the filter's density from accidentally changing while you are shooting, ensuring consistent exposure settings.
This occurs at extreme ND settings on variable ND filters. Rotate the filter ring to a different setting where the effect is less pronounced or absent. Ensure the filter is not used beyond its intended range.
Ensure the filter is clean and free from smudges. Verify that you are within the recommended ND range (3-7 stops) as extreme settings can sometimes impact optical quality. Check that the filter is properly seated on the lens.
Ensure you are aligning the threads correctly. If it feels stiff, try gently wiggling it while turning. Never force the filter, as this can damage the lens or filter threads. Clean the threads on both the lens and the filter if debris is suspected.

Compatibility:
This filter is compatible with any camera lens featuring an 82mm front filter thread. It can be stacked with other filters (like polarizers or graduated NDs), though this may increase the risk of vignetting, especially on wider lenses, and potentially impact image quality.
