Diffusion camera filter Hoya Mist Diffuser Black No1 55 mm

The HOYA Mist Diffuser Black No1 55 mm is a diffusion camera filter that produces a black mist effect by distributing a fine black nano powder between two layers of optical glass. With an uncoated glass surface and a low-profile aluminium frame, the filter softens highlights, slightly reduces shadow contrast and produces a cinematic, vintage look directly in-camera without post-processing.

Advantages

The Mist Diffuser Black No1 provides a repeatable diffusion effect suited for both photo and video work, creating enhanced flares and a controlled softening of bright points. Because the glass is not coated and the nano powder is evenly distributed, the filter delivers consistent misting without whitening the image. Its aluminium low-profile frame improves durability while reducing the risk of vignetting on wide-angle lenses.

Suitable for

• Portraits — smoothing skin texture and reducing overall contrast
• Landscape and nature — softening light through foliage and creating atmosphere
• Night and backlit scenes — enhancing highlights and flares in low-light situations
• Videography — achieving a vintage cinematic diffusion directly on set

How to use

Screw the 55 mm filter onto a matching lens thread and compose as usual. Use the filter to diffuse bright light sources and soften details; the effect becomes stronger with longer focal lengths and when the exposure is compensated brighter. Check the viewfinder or monitor as the perceived effect on-screen may differ from the captured result depending on printing or display size.

Usage recommendations

Choose No1 when you need a stronger diffusion effect, especially for forward-lit or low-light scenes. For subtler softening, consider the No0.5 variant. Be aware that effect strength varies with focal length, light source type and exposure settings; adjust exposure compensation if necessary.
