Camera lens Mist filter Calumet CALSAB1482 — 82 mm, screw-in, single pack

Calumet CALSAB1482 is an 82 mm screw-in Black Mist (mist/diffusion) filter supplied as a single unit in a slim metal mount. The filter combines a transparent optical element made from Japanese AGC glass with a black aerospace-aluminium frame and 28 multilayer coatings to produce controlled diffusion: it slightly lowers contrast, softens highlights and adds a subtle glow around bright points while maintaining neutral colour balance. The ultra-slim 3.3 mm frame has unscrewing tabs for easier handling and double threading for stacking with other filters or accessories; a protective storage box is included.

Advantages

The 28-layer coating system provides anti-reflective, hydrophobic, oleophobic and scratch-resistant protection that keeps the glass easier to clean and prolongs service life without degrading image quality. Japanese AGC glass and a neutral transmission ensure colour fidelity while the diffusion structure creates a gentle blur and glow useful for portrait, cinematic, night and landscape work. The slim aluminium mount reduces vignetting on wide-angle lenses and the included tabs simplify attachment and removal.

Suitable for

• Portrait photography to soften facial details and reduce the appearance of small skin imperfections
• Cinematic and video shoots requiring controlled glow and diffusion for a film-like look
• Landscape and sunrise/sunset scenes where a dreamlike atmosphere and softened highlights are desired
• Night and urban photography to tame specular highlights and create atmospheric light blooms
• Photographers seeking to imitate analog/film characteristics or reduce harsh contrast

How to use

Screw the filter onto a lens with an 82 mm thread by aligning threads and turning clockwise until seated; use the frame tabs to tighten or loosen if necessary. When composing, be aware that highlights will exhibit a subtle halo and overall sharpness will be gently reduced—adjust aperture, focus and exposure to compensate for the desired diffusion level. For stacked use, take advantage of the double threading to combine this filter with other filters or a polarizer, but check for vignetting on wide-angle setups. Clean the filter using a soft blower, microfiber cloth and appropriate lens cleaner to preserve the coatings.

Usage recommendations

Choose the Black Mist filter when you need controlled glow without colour shifts: use a weaker diffusion for portraits and a stronger visual effect for night scenes or creative landscape work. Store the filter in its protective box when not in use to preserve coatings and mechanical parts.
