Camera filter Massa NDx4 screw-in 52mm, neutral density glass filter

The Massa NDx4 screw-in 52mm neutral density glass filter reduces incoming light by two stops, allowing photographers to use longer shutter speeds or wider apertures in bright conditions. Designed for lenses with a 52 mm filter thread, this neutral density filter provides consistent attenuation across the visible spectrum without changing color balance, enabling controlled exposure, motion blur effects and greater creative flexibility in outdoor and studio shooting.

Advantages

The optical glass construction delivers uniform light reduction with minimal impact on image color and sharpness. The screw-in 52mm mount ensures a secure, low-profile fit on compatible lenses and maintains parfocal performance for multi-lens setups. By reducing exposure by two stops, the NDx4 filter helps achieve smoother water, cloud motion and selective subject separation through wider apertures, while being compact and easy to carry in a camera bag.

Suitable for

• Landscape photography — to produce long-exposure effects such as smooth water or streaked clouds
• Portraits in bright light — to use wider apertures for shallow depth of field without overexposure
• Long-exposure creative shots — to intentionally blur motion for artistic effects
• Architecture and cityscapes — to control reflections and balance exposure in high-contrast scenes

Key specifications

• Filter type: Neutral density (ND) — 2 stops (NDx4)
• Mount: Screw-in filter thread
• Filter thread size: 52 mm
• Material: Optical glass element (neutral density)
• Finish: Slim metal frame for reduced vignetting on wide-angle lenses

How to use

Screw the Massa NDx4 filter onto the front thread of a compatible 52 mm lens until secure, taking care not to overtighten. Compose and meter the scene as usual; when using aperture-priority or manual exposure modes, account for the two-stop light reduction by increasing exposure time or opening the aperture accordingly. For long-exposure shots, use a tripod and remote shutter release or camera timer to avoid camera shake. Remove the filter when it is no longer needed to restore normal exposure levels.

Usage recommendations

Store the filter in a protective pouch when not in use to prevent scratches and dust. Clean the glass with a microfiber cloth and appropriate lens cleaning solution. When stacking filters, be mindful of potential vignetting on wide-angle lenses and check for color cast in mixed lighting; use single-filter operation where possible for the cleanest results.
