Neutral density camera filter Calumet CALSAN0482 — 82 mm, single-piece, black/transparent

Calumet CALSAN0482 is an 82 mm neutral density (ND) camera filter supplied as a single-piece accessory. The filter reduces the amount of light entering the lens to enable longer shutter speeds or wider apertures in bright conditions while maintaining neutral color balance. Finished with a black outer ring and a transparent optical surface, this ND filter is designed for landscape, long-exposure, motion-blur photography and situations where control over exposure and depth of field is required.

Advantages

The Calumet ND filter features 28 multi-layer coatings that improve light transmission uniformity, minimize reflections and help resist scratches and moisture. Its slim profile reduces the risk of vignetting on wide-angle lenses while the single-piece construction provides simple mounting on lenses with an 82 mm thread. By blocking light evenly across the optical surface, the filter preserves image color neutrality and detail while allowing extended shutter speeds and larger apertures.

Suitable for

• Landscape photography — creating smooth water and cloud motion with long exposures
• Portraits in bright light — using wide apertures for shallow depth of field and bokeh
• Architectural and urban photography — long exposures to reduce moving subjects
• Video production — maintaining appropriate shutter speed and aperture in bright conditions

Key specifications

• Optical surface: transparent neutral glass
• Coating: 28 multi-layer coatings for reduced reflections and improved durability
• Finish: black filter ring
• Construction: single-piece slim profile to limit vignetting
• Protective properties: water-repellent and scratch-resistant coated surface

How to use

Mount the Calumet CALSAN0482 onto any lens with an 82 mm front thread by screwing it on until secure; avoid overtightening. Compose the shot and set a base exposure for the scene, then adjust shutter speed or aperture to achieve the desired effect: increase shutter duration for motion blur or open the aperture for shallow depth of field while keeping exposure balanced. When using long exposures, use a sturdy tripod and, if available, a remote release or camera timer to minimize vibration. Clean the filter surface with a soft microfiber cloth and appropriate lens cleaner to maintain optical quality.

Usage recommendations

For best results when creating long-exposure images, use a tripod, disable image stabilization if recommended by your lens or camera manufacturer for tripod use, and bracket exposures if unsure about shutter time. When combining ND filtration with additional polarizing filters, check for vignetting and adjust composition or use a slim-profile polarizer. Store the filter in its protective case when not in use to preserve the coatings.
