Polarizing Filter BRAUN CP-L BlueLine 46 mm

Circular polarizing filter BRAUN CP-L BlueLine 46 mm is a screw-in photographic filter designed to reduce unwanted reflections, deepen color saturation and increase contrast in outdoor and landscape photography. The filter mounts on lenses with a 46 mm front thread and is suitable for use with DSLR and mirrorless systems to control glare from water, glass and foliage, improving image clarity and color rendition without altering exposure significantly.

Advantages

The BlueLine polarizer provides uniform polarization across the image circle while maintaining natural color balance. Its circular design allows compatibility with modern autofocus and metering systems. The optically neutral filter surface reduces stray reflections and helps produce richer skies, deeper greens and crisper detail in bright conditions. Lightweight construction and standard 46 mm threading make it easy to attach and remove, and it works with a wide range of lenses that accept 46 mm filters.

Suitable for

• Landscape and nature photography to enhance skies and foliage
• Reducing reflections on water, glass and other non-metallic surfaces
• Outdoor portrait and travel photography where improved color saturation is desired
• Use with DSLR and mirrorless camera lenses that have a 46 mm front thread

Key specifications

• Filter type: Circular polarizer
• Diameter (front thread): 46 mm
• Function: Reduces glare, enhances color saturation and contrast
• Compatibility: Lenses with 46 mm filter thread; compatible with AF and exposure metering systems
• Construction: Slim screw-in mount suitable for general-purpose lenses

How to use

Screw the polarizing filter onto the front thread of a lens with a 46 mm diameter until it is secure but not overly tight. Rotate the filter ring while looking through the viewfinder or live view to adjust the degree of polarization; the effect is strongest at a 90-degree angle to the sun. Compose and meter as usual—circular polarizers are designed to preserve autofocus and exposure metering. In low light, account for the light loss caused by polarization and adjust exposure settings as necessary.

Usage recommendations

For best results, use the polarizer when the sun is to the side of the camera to maximize sky darkening and color saturation. Avoid using the filter at very wide angles with ultra-wide lenses where vignetting or uneven polarization can occur. Store the filter in a protective case when not in use to prevent scratches and dust accumulation.
