Neutral density camera filter Calumet CALSAN0877 77 mm, 1 pc, black/transparent

The Calumet CALSAN0877 is a neutral density (ND) camera filter with a 77 mm thread size supplied as a single piece. Designed for photographers who need to reduce the amount of light entering the lens without altering color balance, this ND filter enables longer shutter speeds and wider apertures under bright conditions. The optical element is transparent while the mount is finished in black. Multi-layer coatings increase light transmission uniformity and help preserve image quality.

Advantages

The Calumet CALSAN0877 uses 28 layers of anti-reflective and protective coatings to minimise flare and reflections while maintaining contrast and colour neutrality. As an ND8-class filter, it reduces incoming light to allow extended exposures and greater control over depth of field. The slim profile helps avoid vignetting on wide-angle lenses, and the coated surface adds water-repellent and scratch-resistant properties for improved durability and easier cleaning.

Suitable for

• Landscape photography — creating smooth water and cloud motion using long exposures
• Long exposure and motion blur — capturing motion trails and softening moving elements
• Portraits in bright light — using wide apertures to achieve shallow depth of field and pleasing bokeh
• Outdoor video — keeping correct shutter speeds and aperture settings under strong lighting
• Architectural and street photography — separating moving subjects from static scenes with extended exposures

How to use

Attach the Calumet 77 mm ND filter to a lens with a matching 77 mm front thread, ensuring threads are aligned and the filter is gently screwed on until secure. Use the filter when you need to reduce light intake: for long exposures, slow the shutter speed and use a tripod to avoid camera shake; for shallow depth of field in bright light, open the aperture while compensating exposure with the filter. Check autofocus and exposure metering after fitting the filter; when necessary, use manual focus or exposure lock for precise results. Clean the glass with a suitable lens cloth and blower before shooting to avoid marks in long-exposure images.

Usage recommendations

For best results in long-exposure landscape or architectural work, combine the Calumet 77 mm ND8 filter with a sturdy tripod and a remote shutter release or camera timer to eliminate vibration. When shooting in mixed lighting, bracket exposures and review histograms to ensure highlight detail is preserved. Store the filter in its protective case when not in use to maintain the coating performance.
