Neutral density camera filter, Calumet CALSAN1652, 52 mm, single-piece, black/translucent

Calumet CALSAN1652 is a 52 mm neutral density (ND) camera filter supplied as a single-piece screw-on filter. The ND glass reduces the amount of light entering the lens, enabling longer exposures or wider apertures without overexposure. The filter has a black slim frame with transparent coated glass and is suitable for landscape photography, motion blur effects and exposure control in bright conditions. The optical surface features multiple coatings for improved image quality and protection.

Advantages

The single-piece Calumet 52 mm ND filter offers controlled light reduction to extend shutter speed and permit wider apertures in bright scenes while maintaining image sharpness. Multiple anti-reflective and protective coating layers enhance contrast and reduce flare and ghosting. Its slim black frame minimizes vignetting on wide-angle lenses and the coated glass provides additional resistance to scratches, water and surface contaminants.

Suitable for

• Landscape photography with long exposures (waterfalls, seascapes)
• Creating motion blur for moving subjects (cars, clouds, water)
• Controlling depth of field in bright light for portrait or product shots
• Video work requiring consistent shutter speeds and natural motion blur

Key specifications

• Filter type: Neutral density (ND)
• Thread size: 52 mm
• Construction: single-piece screw-on filter with slim black frame
• Optical surface: multi-coated glass for reduced reflections and improved contrast
• Finish: transparent coated glass with protective layers
• Intended uses: exposure reduction for longer shutter speeds and wider apertures

How to use

Attach the filter by screwing it onto a lens with a 52 mm front thread until it is secure but not overtightened. Use the filter to reduce incoming light when you need longer shutter speeds or wish to open the aperture in bright conditions. Compose and focus before switching to long-exposure settings when possible; for very long exposures, use a tripod and, if available, remote release or camera timer to avoid camera shake. Clean the coated glass with a soft microfiber cloth and appropriate lens cleaner to maintain optical performance.

Usage recommendations

For best results when creating motion blur or silky-water effects, combine the Calumet 52 mm ND filter with a stable tripod, compose and focus without the filter if your camera has difficulty autofocusing through ND glass, and bracket exposures to find the optimal shutter time. Store the filter in a protective case when not in use to preserve the coatings and surfaces.
