Polarising camera filter BRAUN 72mm Blueline circular polariser, filter size 7.2 cm, black

BRAUN Blueline 72mm circular polarising filter (7.2 cm) is designed to reduce reflections and glare from non-metallic surfaces, increase colour saturation and contrast in skies, and enhance overall clarity for outdoor photography. The filter uses high-quality optical glass in a slim black metal threaded mount that fits lenses with a 72mm filter thread. The circular polariser rotates in its mount to precisely control the degree of polarization and is suitable as lens protection when mounted.

Advantages

The circular polariser decreases unwanted reflections from water, glass and foliage while improving colour depth and contrast without affecting exposure significantly. Constructed from high-quality optical glass with a durable black metal ring, the filter provides reliable mechanical alignment, smooth rotation and consistent performance across the visible spectrum. Its thread form allows secure attachment to lenses with a 72mm filter thread and compatibility with screw-in lens caps and thin filter stacking.

Suitable for

• Landscape photography to deepen sky tones and reduce atmospheric haze
• Travel and outdoor photography where reflections from water or wet surfaces are present
• Architectural and city photography to cut window and glass reflections
• General use as a protective filter for front lens element

Key specifications

• Filter type: circular polarising filter (CPL)
• Filter diameter: 72 mm (7.2 cm)
• Glass: high-quality optical glass
• Mount material: black metal threaded ring
• Rotation: 360° rotatable ring for polarization adjustment
• Primary functions: glare reduction, increased colour saturation and contrast, lens front protection

How to use

Screw the filter onto the front thread of a compatible lens (72 mm). Hold the camera and rotate the outer ring of the filter while observing the scene through the viewfinder or live view until the desired reduction in reflections or increase in sky contrast is achieved. For maximum effect, use the filter at a 90° angle to the sun. Metering may require slight adjustment depending on polarization strength; exposure compensation or manual exposure can be used if the camera's auto-exposure changes.

Usage recommendations

To avoid vignetting on wide-angle lenses, check for clearance when stacking filters and consider using a slim mount if necessary. Keep the optical surfaces clean with a microfiber cloth and store the filter in a protective case when not in use to maintain optical quality.
