Neutral density camera filter Proline 55mm ND 0.9 (8×) for long exposure

Neutral density camera filter B+W 55mm ND 0.9-8X for long exposure designed for photographic use to reduce light entering the lens by 0.9 (8×) stops. The filter fits lenses with 55mm front thread and is intended for long-exposure photography to achieve motion blur or control exposure in bright conditions.

Advantages

The B+W 55mm ND 0.9-8X filter provides consistent light reduction across the frame without introducing color casts. Its neutral density characteristic preserves color fidelity while allowing slower shutter speeds. The circular 55mm filter format keeps lens balance and compatibility with standard screw-in filter mounting.

Suitable for

• Long-exposure landscape photography
• Water and waterfall smoothing
• Urban scenes with moving traffic for motion effects
• Controlling exposure in bright daylight when wider apertures or longer shutter speeds are required

Key specifications

• Model: B+W ND 0.9-8X
• Filter diameter: 55 mm
• Optical density: 0.9 (8× light reduction)
• Type: Neutral density (circular screw-in)

How to use

Screw the filter onto the lens front thread (55mm) until secure. Compose and focus the scene before applying very long exposures, then use the desired shutter speed to achieve the required motion blur or exposure reduction. For manual focus and exposure control, confirm focus and metering with the filter removed or use live view with the filter attached if available.

Usage recommendations

Use a sturdy tripod for long exposures, enable mirror lock-up or electronic shutter if available to reduce camera shake, and check for vignetting on wide-angle lenses when stacking filters.
