Neutral density camera filter Calumet CALSAN0472 — 72 mm, single-piece, black/transparent

Calumet CALSAN0472 is a 72 mm neutral density (ND) camera filter supplied as a single piece with a slim black frame and transparent optical glass. The filter reduces light intensity to allow longer shutter speeds and wider apertures without altering color balance, and its 28-layer multi-coating improves light transmission and surface protection. Designed for lenses with a 72 mm filter thread, this ND filter helps control exposure and depth of field while preserving image quality.

Advantages

The Calumet ND filter uses 28 layers of coating to enhance image contrast and minimize reflections while providing additional protection for the lens surface. Its neutral density effect enables extended shutter speeds and greater control over depth of field, allowing use of wider apertures in bright conditions. The slim, single-piece design reduces the risk of vignetting on wide-angle lenses and the black frame provides a low-profile fit on compatible optics.

Suitable for

• Landscape photography requiring long exposures (waterfalls, flowing water, cloud movement)
• Portraits where shallow depth of field and wide apertures are desired in bright light
• Motion blur and creative long-exposure effects
• Video capture needing maintained shutter speed and natural motion in bright conditions

Key specifications

• Filter type: Neutral Density (ND)
• Filter size: 72 mm thread
• Construction: single-piece filter with slim black frame
• Glass: transparent optical glass with multi-layer coatings
• Coating: 28 layers of anti-reflective/protective coatings
• Effects: reduces light intensity to allow longer exposures and wider apertures without color shift

How to use

Screw the Calumet 72 mm ND filter onto the front of a lens with a matching 72 mm thread. Compose and focus with the filter attached; for very long exposures use a stable tripod and, where possible, a remote shutter release or camera timer to prevent camera shake. Adjust exposure settings to achieve the desired shutter speed and aperture: the neutral density effect reduces incoming light so longer shutter speeds or wider apertures can be used without overexposure. Verify white balance and exposure preview on the camera and fine-tune settings as needed.

Usage recommendations

For best results, pair the ND filter with a tripod for long exposures and check for vignetting when using wide-angle lenses. Clean the coated surfaces with a soft lens cloth and appropriate cleaning fluid to maintain the coating performance. When recording video, set shutter speed according to the desired motion cadence (for example, follow the 180-degree rule) and use the ND filter to keep aperture and exposure consistent in bright conditions.
