Circular Polarizing Camera Filter b&w international Basic Pol MRC 39mm

The Circular Polarizing Camera Filter b&w international Basic Pol MRC 39mm is a screw-in CPL filter designed for lenses with a 39mm filter thread. It reduces reflections and glare from non-metallic surfaces, increases color saturation and contrast, and helps to darken blue skies for improved landscape and outdoor photography. The optical glass is treated with a multi-resistant coating (MRC) to enhance light transmission and provide surface protection against moisture, dirt and minor abrasions.

Advantages

This circular polarizer minimizes unwanted reflections on water, glass and foliage while preserving natural color balance. The rotating mount allows precise control of polarization strength so photographers can adjust reflection suppression and sky darkening in-camera. The multi-resistant coating improves durability and reduces flare and ghosting for clearer images. The slim profile and standard 39mm thread make the filter compatible with compact lenses without significant vignetting.

Suitable for

• Landscape and nature photography to enhance skies and foliage
• Outdoor portraiture to reduce specular highlights on skin and surfaces
• Architectural and product photography to control reflections on glass and polished surfaces
• Travel and compact system setups requiring a 39mm filter thread

Key specifications

• Filter type: circular polarizing (CPL)
• Thread size: 39 mm
• Coating: multi-resistant coating (MRC) for improved transmission and surface protection
• Mount: rotating ring for adjustable polarization
• Profile: slim design to reduce vignetting on wide-angle lenses with 39mm thread

How to use

Screw the CPL filter onto the front of a lens with a 39mm filter thread until it is secure but not overtightened. To change the polarization effect, rotate the outer ring while viewing through the viewfinder or live view until reflections are reduced and the desired color saturation or sky contrast is achieved. For long exposures or multiple stacked filters, check for vignetting and adjust composition or use a different filter combination if necessary. Clean the coated surfaces with a soft lens cloth and appropriate cleaning fluid to maintain optical performance.

Usage recommendations

Use the filter at angles where polarization is effective (typically 90 degrees to the sun) to maximize reflection reduction and sky darkening. Avoid using a polarizer with ultra-wide adapters on lenses that may produce uneven polarization across the frame. Store the filter in a protective case when not in use to preserve the multi-resistant coating and glass clarity.
