Circular Polarizing Filter Schneider Electric Praktica C-Pol 28mm (MPN 01440)

The Schneider Electric Praktica C-Pol 28mm circular polarizing filter is designed for use with lenses that accept a 28mm screw thread. It reduces surface reflections from non-metallic surfaces, enhances color saturation and tonal contrast, and improves sky rendering and foliage detail in outdoor and landscape photography. The filter is a rotational circular polarizer, allowing precise adjustment of the polarization effect while maintaining autofocus and exposure metering compatibility.

Advantages

This circular polarizer reduces unwanted glare from water, glass and wet surfaces while preserving image sharpness. It increases color saturation and contrast in wide-angle scenes without introducing significant vignetting when used on compatible 28mm thread lenses. The rotational mount provides smooth control over polarization intensity and helps achieve deeper blue skies, more defined clouds and richer greens in vegetation.

Suitable for

• Landscape and nature photography to deepen skies and enhance foliage color
• Outdoor architectural shots to reduce reflections on windows and facades
• Photography of water surfaces to control glare and reveal submerged details
• Travel and street photography when managing reflections and improving color saturation

Key specifications

• Filter type: circular polarizer (C-Pol)
• Mount/thread size: 28 mm screw-in
• Optical effect: polarization to reduce reflections and increase contrast
• Mechanical: rotatable slim ring for adjusting polarization angle
• Compatibility: designed for lenses with 28 mm filter thread

How to use

Screw the filter gently onto the lens filter thread until it seats securely, taking care not to cross-thread. Rotate the outer ring while observing through the viewfinder or on the camera live view to set the desired level of polarization; maximum effect occurs when the filter is perpendicular to the reflective surface. The circular design preserves autofocus and exposure metering functionality. Remove the filter when not needed or when shooting long exposures with neutral density requirements.

Usage recommendations

Use the filter at moderate angles to the sun for best sky darkening and color saturation. On ultra-wide lenses check for vignetting and, if necessary, use a slim-profile adapter or step-up ring to avoid darkening at the corners. Clean the filter surfaces with a soft microfiber cloth and lens cleaning solution to maintain optical performance.
