Mist filter Calumet CALSAB1455 for camera lenses, 55 mm thread, 1 pack

Calumet CALSAB1455 is a Black Mist filter with a 55 mm thread designed to mount directly to compatible lenses for in-camera diffusion. The single-pack filter produces subtle softening of highlights, reduces contrast and creates a delicate glow around light sources to achieve atmospheric portraits, landscapes and night scenes. Constructed with Japanese AGC optical glass and a slim aerospace aluminum frame, the filter integrates a transparent mist element and 28 multilayer coatings to preserve color neutrality, reduce reflections and resist water, grease and scratches.

Advantages

The Calumet Black Mist SMC Ultra Slim filter scatters light to produce a controlled, cinematic diffusion without introducing color shifts thanks to neutral glass and anti-reflective coatings. Twenty-eight multilayer coatings deliver hydrophobic and oleophobic protection, improved cleaning and scratch resistance while the slim 3.3 mm aircraft-grade aluminum frame minimizes vignetting on wide-angle lenses. Built-in tabs and double threading simplify mounting, removal and the use of additional filters or accessories.

Suitable for

• Portrait photography — softens skin details and reduces the visibility of minor imperfections
• Landscape photography — creates a dreamlike, atmospheric look at sunrise and sunset
• Night and city photography — produces gentle glow around artificial light sources
• Film emulation and creative projects — imitates the nostalgic look of analog images

How to use

Screw the Calumet CALSAB1455 onto the lens using the 55 mm male thread; check the lens or lens cap for the thread diameter marked with the Φ symbol to ensure compatibility. Use the small tabs on the frame to tighten or loosen the filter without touching the glass surface. The filter works in-camera — no post-processing is required to achieve the diffusion effect. Select exposure and focus as you normally would, and adjust composition, depth of field and aperture to control the amount of visible glow and softness.

Usage recommendations

For subtle portrait results, pair the mist filter with moderate apertures (e.g., f/2.8–f/5.6) to retain pleasing subject separation while softening skin texture. For stronger atmospheric effects in night or landscape shots, close down the aperture and experiment with point light sources in the frame to emphasize the characteristic halo. Keep the filter clean using a soft microfiber cloth and avoid abrasive cleaners despite the scratch-resistant coating; store the filter in its protective box when not in use.
