Camera lens polarising filter Rollei 26246 77 mm circular polariser

Rollei 26246 77 mm circular polariser is a camera lens filter designed to reduce reflections and increase color saturation for lenses with a 77 mm filter thread. The single-piece, black-framed optical element adjusts polarization to manage glare from non-metallic surfaces such as water, glass and foliage, and to enhance sky and green tones. The filter is intended for landscape, outdoor and architectural photography where contrast control and color saturation are required in bright conditions.

Advantages

This circular polariser allows direct, on-lens control of the polarization effect by rotating the filter ring, enabling continuous reduction or reinforcement of reflections and selective increase of color saturation within the polarizing range. The optical element transmits light with minimal color cast and preserves image contrast while suppressing unwanted reflections. The filter frame is finished in black to minimise stray reflections at the lens edge and is supplied as a single unit for straightforward mounting on lenses with a 77 mm thread.

Suitable for

• Landscape photography to enhance skies and foliage
• Outdoor photography to control glare from water and wet surfaces
• Architectural and product photography to reduce reflections on glass and non-metallic surfaces
• Travel and nature photography where improved contrast and saturation are desired

Key specifications

• Filter type: circular polariser (CPL)
• Suitable thread diameter: 77 mm
• Frame colour: black
• Element: single-piece transparent optical element
• Primary functions: reduce reflections, increase color saturation, improve contrast
• Surface properties: scratch-resistant coating and water/oil resistance on the optical surface

How to use

Attach the filter to the front of a lens with a 77 mm filter thread and rotate the outer ring while observing the viewfinder or live view to set the desired level of polarization. For strongest sky and foliage enhancement, rotate the filter until the sky appears deepest in tone at approximately 90 degrees to the sun. To reduce reflections on water or glass, rotate until the reflected highlights are diminished. Check exposure after installing the filter and adjust settings if needed, as polarizers can reduce light transmission by a variable amount.

Usage recommendations

Store the filter in a protective case when not in use, and clean the optical surface with a soft microfiber cloth and suitable lens cleaner to preserve the scratch-resistant coating and maintain neutral color transmission.
