Neutral density camera filter Calumet CALSAN1677 77 mm, 1 pc, neutral density

Calumet CALSAN1677 is a 77 mm neutral density (ND) camera filter supplied as a single piece. Engineered to reduce the amount of light entering the lens without altering color balance, this ND filter enables longer shutter speeds and the use of wider apertures in bright conditions. The filter’s slim design and multi-layer coating preserve image clarity while fitting lenses with a 77 mm thread, making it suitable for landscape, long-exposure and motion-blur photography.

Advantages

The Calumet CALSAN1677 features 28 layers of multi-coating that improve light transmission uniformity and resist reflections. Its neutral density characteristic provides consistent exposure reduction without introducing unwanted color casts, while the ultra-slim profile minimises vignetting on wide-angle lenses. The coated surface also offers additional protection for the front element of the lens against minor impacts, smudges and water.

Suitable for

• Long-exposure landscape photography (waterfalls, seascapes)
• Portraits with shallow depth of field in bright light
• Motion blur and creative motion effects
• Video shooting that requires controlled shutter speed and aperture

Key specifications

• Filter type: neutral density (ND)
• Filter thread diameter: 77 mm
• Optical density level: ND (reduces incoming light to allow longer exposures and wider apertures)
• Coating: 28 multi-layer coatings for improved transmission and reduced reflections
• Finish/appearance: black/transparent

How to use

Screw the Calumet 77 mm ND filter onto the front thread of a compatible lens until it is secure but not overtightened. Compose and focus the scene without the filter if your camera or lens has difficulty focusing through dense ND; then attach the filter and switch to manual focus if needed. Use a tripod for long exposures to avoid camera shake, and select the longer shutter speed or wider aperture required for your creative effect. When using the filter for video, set the shutter speed appropriate to the frame rate to preserve natural motion blur.

Usage recommendations

Keep the filter clean and store it in a protective case when not in use. For best results with wide-angle lenses, choose an ultra-slim filter design to reduce the risk of vignetting. Wipe the coated surface with a microfiber cloth and appropriate lens cleaner to maintain image quality; avoid excessive pressure to preserve the multi-layer coating.
