Frequently asked questions

What effect is this filter designed to create?

Urth describes it as a stronger diffusion filter that blooms highlights, adds haze and lowers contrast. The maker says the effect works best with bright, close light sources.

Will it fit my lens?

Check that your lens accepts a 55mm filter. For magnetic attachment, the listing says a magnetic adapter ring is included, but confirm the package for the selected offer.

Is the diffusion subtle?

The listing identifies this as ¼ diffusion and calls its haze effect stronger. It may not suit buyers who want to preserve a crisp, neutral image.

What coating does it have?

The listing specifies multi coating and describes 20-layer CoraNano-coated SCHOTT B270 glass. These are manufacturer claims, not independently verified measurements.
