Neutral Density Camera Filter B+W 103, 77 mm, Black

The B+W 103 Neutral Density Camera Filter in 77 mm with a black finish reduces incoming light by three f-stops (log density 0.9) and has a filter factor of 8x. Designed for photographers and videographers, this ND filter enables longer exposure times and the use of wider apertures in bright conditions while maintaining very good color neutrality. The filter glass is single-coated to reduce internal reflections and improve transmission, and it is mounted in the slim B+W F-Pro brass filter ring with a front accessory thread for added versatility.

Advantages

The single-layer anti-reflection coating on each glass surface increases light transmission to over 98% and reduces ghosting and reflections compared to uncoated glass. The three-stop light reduction (0.9 log density) provides controlled exposure for long-exposure landscape shots, motion blur effects and video work where lens stopping is not feasible. The slim F-Pro brass mount minimizes the risk of vignetting on wide-angle lenses and includes a rear-retaining ring that prevents the filter glass from loosening when removing tightly screwed accessories.

Suitable for

• Landscape long-exposure photography to smooth water and cloud motion
• Creative motion blur and slow-shutter effects in daylight
• Video recording when aperture cannot be reduced sufficiently
• Portrait and shallow-depth-of-field shots in bright light using wider apertures
• Lenses with 77 mm filter threads

Key specifications

• Optical density: 0.9 (three f-stops)
• Filter factor: 8x
• Thread diameter: 77 mm
• Coating: single anti-reflection vacuum coating on each glass surface
• Mount: slim B+W F-Pro brass filter mount with front accessory thread
• Color neutrality: very good color neutrality for natural color rendering

How to use

Screw the filter onto any lens with a 77 mm front thread until it is snug; avoid overtightening. Use the filter when you need to reduce exposure by three stops—typical situations include bright daylight long exposures, slowing shutter speed for creative blur, or maintaining a wide aperture for shallow depth of field in bright light. When composing long exposures on a tripod, set your camera exposure and focus before attaching or after attaching the filter as preferred, and confirm metering or use manual exposure adjustments to compensate for the reduced light.

Usage recommendations

For best results, combine the ND filter with a sturdy tripod for long exposures and use mirror lock-up or a remote release to minimize vibration. Clean the filter surfaces with a lens-safe cloth before use and store the filter in its protective case when not in use. When using wide-angle lenses, check for vignetting at extreme focal lengths despite the slim mount; if vignetting occurs, consider using a thinner filter system or stacking fewer accessories.
