# Urth Ethereal ¼ Black Mist Diffusion Filter, 39 mm \(Plus+\)

Urth Ethereal ¼ Black Mist Diffusion Filter \(Plus+\) is a 39 mm screw-on filter designed to soften contrast and create a more pronounced haze around light sources. Its stronger diffusion effect is most suited to portraits and cinematic-style images, but it is a deliberate look rather than a neutral filter.

## At a glance

- The ¼ strength is described as producing more obvious diffusion than the ⅛ version.
- Urth says the filter lowers contrast and creates a stronger haze, particularly with bright, close light sources.
- The manufacturer describes the Plus+ glass as German SCHOTT B270 with a 20-layer CoraNano coating.
- The listed filter factor is 2 x.

## Pros

- A 39 mm thread fits lenses with the matching filter thread, and the listing identifies compatible cameras by that thread size.
- The stronger diffusion effect offers a practical way to soften contrast and sharpness without relying on post-processing.
- The manufacturer claims a slim rim intended to avoid vignetting.

## Cons

- The pronounced haze and softened contrast are specialised effects, so the filter is not suited to photographers seeking an unaltered image.

## Before you buy

- Confirm that the lens has a 39 mm filter thread before purchase. The listing says the filter is not water resistant. Stacking is possible according to the manufacturer, but it recommends using one filter for best image quality and warns that stacking can cause vignetting.
- Listing details are inconsistent: the technical material field says glass, while a feature calls the filter tough magnalium, and the coating is described as water and dust repellent in one section despite the stated water-resistance level of Not Water Resistant. The lens glass is also specified as German SCHOTT B270, while the package materials and any water-repellent performance are not clearly confirmed. Check these details if they matter to your use.

## A good fit for

- Portrait photographers wanting a pronounced diffusion effect and softer skin tones.
- Photographers seeking visible haze and lower contrast around bright, close light sources.
- Users of lenses with a 39 mm filter thread who want a screw-on effect filter.

## Less suited to

- Photographers seeking neutral rendering or only subtle diffusion.
- Users whose lenses do not have a 39 mm filter thread.
- Use in conditions requiring a water-resistant filter.

## Customer feedback

Customer feedback reports positive impressions of quality and performance, with portraits mentioned as a use where buyers appreciated the results. That aligns with the filter's stated portrait-oriented diffusion purpose, but the rating information alone does not establish how strong or consistent the effect will look with a particular lens or lighting setup.
- Positive themes: Customer feedback describes the filter as high quality and notes its performance, particularly for portraits.

## Frequently asked questions

### What effect does this filter create?
Urth describes the ¼ diffusion strength as producing a more obvious softening effect, with lower contrast and haze around bright light sources. The result is a deliberate stylistic effect rather than neutral rendering.
### How do I check whether it fits my lens?
Check the filter-thread diameter marked on the lens, often beside the Ø symbol, or on the lens cap. This filter is listed for a 39 mm thread.
### Can I stack it with other filters?
The manufacturer says the filters are double-threaded for stacking, but recommends using one at a time for best image quality. Stacking can cause vignetting, and it advises against stacking more than two.
