Rollei circular polarising camera filter 6.7 cm (26.33 mm?) model 26330, double-sided coating, black/blue/transparent

Rollei circular polarising camera filter 6.7 cm (26.33 mm?) model 26330 is a single-unit circular polariser with double-sided coating designed to reduce reflections and increase colour saturation for landscape, portrait and architectural photography. The filter fits lenses that accept a 6.7 cm filter diameter and is supplied in a black/blue/transparent finish. Its optical coating reduces unwanted reflections and improves contrast, making it suitable for outdoor shooting where glare control and improved color rendition are required.

Advantages

The double-sided coating decreases surface reflections and helps maintain image clarity during outdoor and landscape work. By reducing glare from non-metallic surfaces such as water and glass, the filter enhances perceived colour saturation without altering composition. The protective coating also repels dirt, oil and water, allowing for easier cleaning and more consistent performance in changing environmental conditions.

Suitable for

• Landscape photography to deepen skies and manage reflections from water and foliage
• Architectural and real-estate photography to reduce window and facade glare
• Portraits shot outdoors to control specular highlights on skin and surrounding surfaces
• Outdoor and travel photography where glare control and colour enhancement are needed

Key specifications

• Filter type: circular polariser (CPL)
• Filter diameter: 6.7 cm (match lenses accepting this diameter)
• Coating: double-sided optical coating with water-, oil- and dirt-repellent properties
• Finish: black/blue/transparent appearance
• Pack: single unit

How to use

Mount the circular polarising filter on a lens that accepts a 6.7 cm filter thread, ensuring it is seated and rotated freely. Compose the shot and then rotate the outer ring of the filter while viewing through the viewfinder or live view until the desired reduction in reflections and increase in colour saturation is achieved. For consistent results in varied light, check the effect at different rotation angles and lock your exposure settings. When shooting long exposures or night scenes, use a tripod and a wired or wireless release to prevent camera movement.

Usage recommendations

When using the filter in mixed or artificial light conditions, monitor white balance and, if available, set manual white balance to maintain accurate colour rendering. Clean the coated surfaces with a soft cloth to preserve the water- and oil-repellent properties and avoid abrasive cleaners that could damage the double-sided coating.
