Neutral density camera filter Kenko Smart Filter ND8 Slim 5.2 cm (52 mm) black

The Kenko Smart Filter ND8 Slim 5.2 cm (52 mm) is a neutral density (ND) camera filter designed to reduce incoming light by 3 stops, allowing longer shutter speeds or wider apertures in bright conditions. Its slim profile and black finish are intended for compact lenses where minimizing vignetting and maintaining a discreet appearance are important. The filter is supplied as a single piece per pack and is suitable for landscape, portrait and motion-blur photography where control over exposure and creative use of motion is required.

Advantages

The ND8 filter enables exposures up to eight times longer without changing aperture, making it possible to create motion blur effects such as soft water flow or cloud movement while keeping correct exposure. Its slim design reduces the incidence of vignetting on wide-angle lenses and the black frame minimizes reflections and light leaks. Built to fit 52 mm lens threads, the filter provides consistent light attenuation and straightforward attachment and removal.

Suitable for

• Landscape photography to smooth water and moving clouds
• Portraits in bright light when a wide aperture is desired
• Long-exposure motion-blur effects for waterfalls and rivers
• Urban and architectural scenes requiring slower shutter speeds

Key specifications

• Filter type: Neutral density (ND) — 3 stops attenuation
• Reduction factor: ND8 (approximately 3 EV stops)
• Mount diameter: 52 mm screw-in
• Profile: Slim frame to limit vignetting on wide-angle lenses
• Finish: Black frame to reduce reflections

How to use

Screw the filter onto the front thread of a 52 mm lens until it is snug; avoid overtightening. Use the filter when ambient light is strong and you want to use a wider aperture for shallow depth of field or extend shutter speed for motion blur. Combine the ND8 with a tripod for multi-second exposures to prevent camera shake, and check exposure with a histogram or test shots to compensate for the 3-stop light reduction.

Usage recommendations

For best results when creating motion blur, mount the camera on a stable tripod, use a remote shutter release or self-timer, and compose with a small adjustment to exposure compensation if needed. When shooting in variable light, consider bracketing exposures to ensure correct exposure with the ND8 in place.
