Neutral density camera filter 55 mm, B+W (b&w international) model 106

B+W neutral density camera filter 55 mm, model 106, is a screw-in optical filter designed to reduce the amount of light entering the lens by six f-stops (filter factor 64×). The single-piece black filter lets you use longer shutter speeds or wider apertures in bright conditions without changing exposure settings. This ND filter is compatible with lenses that accept 55 mm threaded filters and is intended for photographic techniques that require significant light reduction, such as motion blur of water or creating shallow depth of field in strong daylight.

Advantages

This neutral density filter provides a precise 6-stop light reduction while preserving the original colour balance for most wavelengths; it is especially useful when you need longer exposures without overexposure. The filter’s optical glass construction delivers reliable image quality and consistent attenuation across the visible spectrum. Because the filter shows higher transmission in the red beyond 660 nm, images may display a slightly warmer tone; this effect can be corrected by fitting a UV/IR-blocking filter in front of the ND filter if required. The screw-in design ensures secure attachment to lenses with a 55 mm thread.

Suitable for

• Long-exposure landscape photography to smooth water and clouds
• Creating motion blur for moving subjects in daylight
• Using wider apertures outdoors for shallow depth of field
• Architectural and urban photography requiring controlled exposure

Key specifications

• Light reduction: 6 f-stops (filter factor 64×)
• Mount: 55 mm screw-in thread
• Colour effect: slight warming due to higher transmission >660 nm
• Pack: single filter (1 piece)

How to use

Attach the filter to the front of a lens with a 55 mm thread by screwing it on until it is secure but not overtightened. Compose and focus without the filter if necessary, then set the desired exposure compensated for the 6-stop light reduction, or use the camera’s meter with the filter in place and adjust settings accordingly. For very long exposures, use a tripod and, if available, a remote shutter release or camera timer to avoid camera shake. If you require exact neutral colour reproduction, consider using a UV/IR-blocking filter placed in front of the ND filter.

Usage recommendations

Use the filter when you need reliable six-stop attenuation: for example, change 1/60 s to approximately 1 s without altering aperture. When photographing flowing water or busy streets, stabilise the camera on a tripod and check for colour cast; add a UV/IR-blocking filter in front of the ND filter if a warmer tone is undesirable.
