Product Information

Full details

The Urth Variable ND2-32 + 1/4 Black Mist Filter Pro (39mm) is designed for photographers and videographers seeking to control light exposure while adding a cinematic aesthetic to their footage. This filter excels at softening harsh highlights and creating a dreamlike halation effect, making it an ideal tool for portrait and narrative filmmaking; however, users should be aware that the variable ND mechanism may introduce a cross-polarization 'X' effect if pushed beyond its intended 5-stop limit on ultra-wide lenses.

FAQs

Can I use a lens cap with this filter?

Yes, standard lens caps that fit a 39mm thread should fit over the filter, though some tight-fitting caps may be difficult to secure.

Does this filter cause vignetting?

On most standard lenses, the ultra-slim frame is designed to prevent vignetting. However, use caution on ultra-wide angle lenses.

What is the primary benefit of the black mist effect?

It reduces contrast and softens high-frequency details, which is popular for creating a cinematic, dreamy look in digital video.

Can I stack this filter with other filters?

It is not recommended to stack other filters on top of a variable ND, as this increases the likelihood of vignetting and potential optical artifacts.

Is this filter weather-sealed?

While the nano-coating helps repel water and dust, the filter itself is not fully weather-sealed. Avoid prolonged exposure to heavy rain or high moisture.

Troubleshooting

Visible dark cross pattern (X-effect) in the image.

This is common in variable ND filters at high density settings. Slightly rotate the filter back toward the ND2 mark to reduce the intensity until the pattern disappears.

Filter is stuck on the lens.

Avoid squeezing the frame too hard. Use a rubber lens filter wrench to gain a better grip and apply even, gentle counter-clockwise pressure.

Pros and Cons

Pros

  • Combines neutral density and diffusion in one filter for a streamlined workflow
  • High-grade SCHOTT B270 glass offers excellent sharpness
  • Sturdy aerospace-grade aluminum frame
  • Hard stops prevent accidental over-rotation
  • Nano-coating makes the glass easy to clean and smudge-resistant

Cons

  • Small 39mm size limits use to specific compact lenses or requires step-up rings
  • Potential for X-pattern cross-polarization at maximum density settings
  • Cannot use a lens hood while the filter is attached

Setup, Compatibility & Care

To install, gently screw the 39mm filter threads onto the front of your compatible lens. Ensure the filter is seated properly to avoid cross-threading. When adjusting density, use the square-edge grip to rotate the front element; the hard stops will notify you when you have reached the limit of the ND range. For care, always store the filter in its protective case when not in use. Use a dedicated lens cleaning cloth or a blower to remove dust. If the glass becomes smudged, apply a small amount of lens cleaning solution to a microfiber cloth—never directly to the glass—and wipe in a circular motion.
