Camera lens Mist filter Calumet CALSAB1267 67 mm - single-piece black/transparent

The Calumet CALSAB1267 is a 67 mm Black Mist single-piece filter designed to produce a softening diffusion effect for photographic and cinematic use. Constructed with Japanese AGC glass and a slim aerospace aluminium frame, this mist filter scatters light to reduce contrast, introduce a subtle glow around bright areas and gently soften details. The filter features 28 multilayer coatings — including hydrophobic, oleophobic, scratch‑resistant and anti‑reflective treatments — to preserve image quality and simplify cleaning. The slim 3.3 mm housing includes unscrewing tabs and a double-thread design that supports stacking with other filters or accessories. A protective storage box is included for transport and safekeeping.

Advantages

The Calumet Black Mist SMC Ultra Slim filter creates a natural diffusion effect while maintaining neutral colour balance thanks to high-quality AGC glass. Multiple coatings reduce reflections, repel water and grease, and protect the surface from scratches, extending service life and reducing maintenance. The ultra-slim aluminium frame minimises vignetting on wide-angle lenses, and the unscrewing tabs make fitting and removal straightforward. Double threading increases flexibility by allowing additional filters or accessories to be mounted simultaneously.

Suitable for

• Portrait photography to soften skin texture and reduce contrast
• Wedding and event photography for a gentle, atmospheric look

How to use

Screw the Calumet 67 mm Black Mist filter onto a lens with a matching 67 mm thread until it is snug; use the frame tabs if additional grip is needed for removal. Because the filter produces diffusion and halation, framing and exposure should be checked after mounting — adjust aperture, focus and exposure compensation as required to achieve the intended softness and highlight behavior. If stacking filters, attach the primary filter first and then screw on the second filter or accessory to the outer thread. Clean the filter using a soft microfiber cloth and appropriate lens cleaning solution to preserve coatings.

Usage recommendations

For portraits, use the mist filter with moderate diffusion strength and stop down or recompose to preserve sufficient facial detail. For cinematic or night scenes, experiment with highlights to control halation; lower contrast settings and slightly reduced clarity in post can complement the filter’s effect. Avoid abrasive cleaners to protect the multilayer coatings and store the filter in the supplied box when not in use.
