1 / 7Urth 43mm Magnetic Ethereal Black Mist ½ Diffusion Filter Plus
The Urth Magnetic Ethereal Black Mist ½ Diffusion Filter Plus is a magnetic 43mm lens filter designed to scatter light for a stronger haze and lower contrast. Its effect is most pronounced with bright, nearby light sources, so it suits photographers and filmmakers seeking a deliberately softened, cinematic rendering rather than an unaltered image.
At a glance
- The listing describes a half-strength black mist effect that visibly scatters light, softens highlights and reduces contrast.
- The manufacturer says the filter is made from SCHOTT B270 glass with a 20-layer CoraNano coating.
- Magnetic attachment is intended to make attaching, stacking and switching filters quicker.
- A protective travel case is mentioned in the product description.

View offerAhead of Black FridayExplore the selectionPros and cons
Pros
- The 43mm thread size gives a clear fit criterion for compatible camera lenses.
- A diffusion effect is useful when a softer, hazier look is wanted in-camera, particularly around bright, close light sources.
- The magnetic design is intended to speed up filter changes and support stacking.
Cons
- The diffusion effect is intentionally visible and may not suit images where crisp highlights and natural contrast are priorities.
- This filter only fits lenses with a 43mm filter thread, so it will not directly fit other thread sizes.

What to know before buying
Listing details to confirm
The listing calls the item both a magnetic filter and a threaded 43mm filter, but does not explain whether magnetic mounting requires a separate adapter or what mounting parts are included. Confirm the mounting method and any required parts for your lens. The listed screen size also repeats 43mm, which appears to be a filter specification rather than a separate display. The 2 x filter factor is supplied without an explanation of its meaning. Product-page claims about the glass, coating, water resistance and lifetime backing are not independent verification.
Who is it for?
A good fit for
- Photographers using a 43mm filter thread who want a strong, visible diffusion effect and softened highlights.
- Portrait or video work where the intended look is hazier and lower in contrast, especially with bright nearby light sources.
Less suited to
- Photographers seeking a neutral filter or minimal changes to sharp-looking highlights and contrast.
- Anyone whose lens does not have a 43mm filter thread, unless they have a suitable compatible mounting solution.
