Camera lens Mist filter Calumet CALSAB1277 77 mm, black/transparent, 1 pc

Calumet CALSAB1277 is a 77 mm Mist camera lens filter that softens highlights, reduces contrast and creates a subtle glow and diffusion effect. Housed in an ultra-slim black aluminum frame with tabs for easy handling, the single-piece filter uses Japanese AGC glass and a 6H hardness surface to preserve optical clarity while providing a gentle atmospheric blur. The Mist element is multilayer-coated to resist water, oil, scratches and reflections, and the kit includes a protective box for safe storage and transport.

Advantages

The Calumet Black Mist SMC Ultra Slim filter features 28 multilayer coatings that provide hydrophobic, oleophobic, scratch-resistant and anti-reflective protection without altering color balance. Its ultra-slim 3.3 mm aerospace aluminum frame minimizes vignetting on wide-angle lenses and includes convenient unscrewing tabs. Japanese AGC glass ensures neutral color rendering and reliable mechanical durability, while the double threading enables stacking with additional filters or accessories.

Suitable for

• Portrait and beauty photography where subtle diffusion improves skin tones
• Fashion and editorial shoots requiring controlled highlight bloom
• Cinematic and narrative filmmaking to create a nostalgic or dreamy atmosphere

How to use

Screw the Calumet 77 mm Mist filter onto a lens with a matching 77 mm thread until it is secure; use the tabs on the frame to assist unscrewing if needed. Use the filter to soften highlights and reduce local contrast: select aperture, exposure and focus as you normally would, then evaluate the effect in the viewfinder or on the monitor. For stronger diffusion, pair the filter with longer focal lengths or move closer to the subject; for subtler results, stop down the aperture or combine with a weaker diffusion element. When stacking filters, ensure both threads are properly seated to avoid cross-threading.

Usage recommendations

Choose the level of mist effect based on the scene: weaker diffusion for portrait work to preserve detail, stronger diffusion for night scenes or stylized cinematic looks. Keep the filter clean using a soft brush and lens cloth; the multilayer coatings help repel moisture and oils but gentle cleaning prolongs coating life. Store the filter in the supplied protective box when not in use and avoid overtightening to maintain the frame and threads.
