Urth Variable ND2-32 Filter Pro - 72mm

A variable ND filter offers a range of light reduction (1-5 stops here) that you can adjust, providing flexibility. Fixed ND filters offer a single, specific amount of light reduction (e.g., ND8, ND64).

This specific model is for 72mm lenses. For other lens sizes, you would need to purchase a Urth Variable ND2-32 Filter Pro in the appropriate size (e.g., 49mm, 82mm).

The 'ND2-32' refers to the range of light reduction, approximately 1 to 5 stops. ND2 is equivalent to 1 stop, and ND32 is equivalent to 5 stops.

The filter uses premium SCHOTT B270 optical glass and advanced coatings, designed to maintain high optical clarity and minimize impact on image sharpness.

Use a soft lens brush to remove dust, or a clean microfiber cloth. For smudges, use a lens cleaning solution sparingly on the cloth, not directly on the filter.

The hard-stop is a physical limit built into the rotation mechanism. It prevents you from over-rotating the filter, which can cause X-patterns or uneven darkening, and ensures consistent results.

This usually occurs at extreme ends of the variable ND range. Rotate the filter ring back towards the minimum ND setting (ND2) until the X-pattern disappears. Ensure you are within the 1-5 stop range.

Ensure the filter is clean. While designed for color neutrality, check for strong light sources that might interact with the filter. Try adjusting white balance in post-production. If the cast persists across all settings, verify the filter is functioning correctly.

Check for any debris or damage on the lens threads or the filter threads. Ensure you are using the correct filter size (72mm). Screw the filter on gently and straight, without forcing it.
