Neutral density camera filter 72 mm — Calumet CALSAN0872

Calumet CALSAN0872 is a 72 mm neutral density (ND) camera filter designed to reduce the amount of light entering the lens, enabling longer exposures or wider apertures while preserving image quality. Constructed as a single-piece, slim filter with multi-layer coating, it fits lenses with a 72 mm thread and is supplied as one unit per pack. The filter is intended to control exposure in bright conditions, create motion blur effects such as silky water, and allow a shallower depth of field for stronger subject separation.

Advantages

The Calumet ND filter features an ultra-slim profile and 28-layer multi-coating that improves optical transmission and reduces reflections, helping to maintain contrast and color fidelity. Its neutral light reduction provides predictable exposure control without altering color balance, and the slim construction reduces the risk of vignetting on wide-angle lenses. The single-unit design is easy to mount and remove on lenses with a 72 mm filter thread.

Suitable for

• Landscape photography — long exposures to smooth water and cloud movement
• Portraits — using wide apertures in bright light to achieve shallow depth of field and pleasing bokeh
• Architectural and city scenes — long exposures to reduce moving people and traffic
• Video production — maintaining cinematic shutter speeds and aperture in bright conditions

Key specifications

• Construction: single-piece ultra-slim frame
• Coating: 28-layer multi-coating for improved transmission and reduced reflections
• Finish: black frame with transparent optical glass
• Quantity: 1 piece per pack

How to use

Screw the filter onto the front of any lens that has a 72 mm thread until it is seated securely but not overtightened. Compose and meter the scene as usual; when the filter is attached, expected exposure values will change according to the filter's light reduction (ND8 / 3 stops). For long-exposure shots use a tripod to avoid camera shake and adjust shutter speed to achieve the desired motion blur. For shallow depth of field in bright light, open the lens aperture and adjust shutter speed or ISO to maintain correct exposure.

Usage recommendations

To minimise reflections and maintain image clarity, clean the filter surfaces with a soft microfiber cloth before use and store the filter in a protective case when not in use. When shooting wide-angle lenses, check for vignetting and, if present, consider using the ultra-slim profile or stepping up to a larger filter size with a step-up ring.
