Neutral density camera filter Calumet CALSAN1682 — 82 mm, 1 pc, black/transparent

Calumet CALSAN1682 is an 82 mm neutral density (ND) camera filter that reduces the amount of light entering the lens without changing color balance. The single-piece, black/transparent optical element is designed for use with lenses featuring an 82 mm filter thread and is intended to extend shutter speeds, control depth of field in bright conditions and produce motion blur effects while preserving image quality. The filter is treated with 28 layers of multi-coating to improve transmission, reduce reflections and provide added protection for the front element of the lens.

Advantages

The Calumet CALSAN1682 ND filter provides consistent light reduction across the frame and maintains neutral color rendering. Its ultra-slim profile minimizes vignetting on wide-angle lenses while the 28-layer SMC coating improves contrast, reduces flare and increases scratch and water resistance. The filter enables longer exposures and wider aperture choices in bright environments without introducing color casts or significant loss of sharpness.

Suitable for

• Long-exposure landscape photography (waterfalls, seascapes, clouds)
• Creating motion blur for moving subjects (traffic, crowds)
• Portraits in bright light with shallow depth of field and bokeh
• Video shooting to control shutter speed and preserve cinematic motion
• Architectural photography requiring removal of moving elements via long exposures

• Color/finish: black frame with transparent neutral glass

How to use

Thread the Calumet CALSAN1682 onto a lens with an 82 mm front thread and ensure it is tightened securely but not overtightened. Compose and meter the scene as you normally would; when using the ND filter, the camera’s exposure meter will indicate the reduced light level so you can set a longer shutter speed or larger aperture accordingly. For very long exposures use a tripod, remote release or camera timer to avoid camera shake. When shooting video, adjust aperture and shutter speed to maintain correct exposure and natural motion blur.

Usage recommendations

Use the filter in combination with a sturdy tripod for long exposures and check for vignetting when using wide-angle lenses. Clean the coated surfaces with a microfiber cloth and appropriate lens cleaner to preserve the multi-coating. When not in use, store the filter in its protective case to avoid scratches and contamination.
