Camera lens neutral density filter Calumet CALSAN0477 77 mm

Calumet CALSAN0477 is a 77 mm neutral density (ND) camera lens filter that reduces the amount of light entering the lens without changing color balance. Designed for photographers and videographers who need to control exposure and depth of field in bright conditions, this single 77 mm filter features an ultra-slim profile and multi-layer coating to maintain image quality while allowing longer shutter speeds or wider apertures.

Advantages

The Calumet CALSAN0477 ND filter provides controlled attenuation of light to enable extended shutter speeds and shallower depth of field in strong lighting. Its 28-layer coating improves light transmission consistency and surface protection, while the slim design minimises vignetting on wide-angle lenses. The filter is supplied as a single 77 mm unit in a black/transparent finish and is suitable for both stills and video work.

Suitable for

• Landscape photography where long exposures create motion blur in water and clouds
• Portrait photography requiring wide apertures in bright conditions to achieve shallow depth of field
• Video production where maintaining cinematic shutter speed and aperture in daylight is needed
• Architectural photography using long exposures to minimise moving subjects

Key specifications

• Filter type: neutral density (ND)
• Diameter: 77 mm
• Optical density options: ND4x / ND8x / ND16x family (this model: ND4)
• Coating: 28 multilayer coatings for improved transmission and surface protection
• Finish: black/transparent
• Design: ultra-slim profile to reduce vignetting on wide-angle lenses

How to use

Attach the Calumet 77 mm ND filter to a lens with a matching 77 mm filter thread by carefully screwing it onto the front element until secure. Use the filter to reduce incoming light and then set a longer shutter speed or open the aperture as required by your creative intent. For video, select shutter speed and aperture that preserve natural motion and depth of field; for long-exposure stills, use a tripod to keep the camera steady during extended exposures. Remove or store the filter when not in use to avoid accidental marks.

Прекомендации по использованию

To preserve coating performance and image quality, clean the filter with a soft microfiber cloth and a dedicated lens cleaner. Avoid applying excessive force when mounting or removing the filter to prevent cross-threading. When using very wide-angle lenses, check for vignetting and consider stacking filters only if necessary.
