## Long description

The Circular Polarizing Filter B+W T-Pro KSM HTC CPL MRC nano 37mm is a screw-in lens accessory designed to reduce reflections from non-metallic surfaces, increase color saturation and contrast, and improve sky rendering in outdoor and landscape photography. Compatible with lenses that have a 37mm front thread, this CPL filter uses multiple layers of anti-reflective and protective coatings to maintain image quality while offering easier cleaning and enhanced resistance to moisture and dirt.
Advantages
This CPL filter provides noticeable reduction of surface reflections and glare without affecting exposure settings. The multi-resistant coating (MRC) minimizes internal reflections and ghosting, while the nano topcoat improves water and oil repellence for simpler cleaning. The slim, precisely machined frame helps avoid vignetting on wide-angle lenses and ensures secure mounting. Overall, the construction balances optical clarity with practical handling for outdoor use.
Suitable for
Landscape and nature photography to deepen sky tones and reduce haze
Outdoor product photography to control reflections on glass and water
Architectural and street photography when removing window or pavement glare
Any shooting situation with a lens that has a 37mm front thread
Key specifications
Filter type: circular polarizer (CPL)
Thread size: 37mm front thread
Coatings: multi-resistant coating (MRC) plus nano topcoat
Mount: slim metal filter ring to reduce vignetting
Optical use: reduces reflections, increases color saturation and contrast
How to use
Screw the filter gently onto the lens front thread until secure, taking care not to cross-thread. Rotate the filter ring while observing through the viewfinder or on the camera monitor to adjust the degree of polarization until reflections are minimized and desired contrast is achieved. Because the filter reduces the amount of light entering the lens, compensate exposure settings as needed, especially at smaller apertures or in low light. Remove the filter for night photography or when polarization effects are not desired.
Usage recommendations
Clean the filter surface with a soft microfiber cloth and, if necessary, a small amount of lens cleaning solution. Store the filter in its protective case when not in use to preserve the coatings. When shooting at extreme angles to reflective surfaces, rotate the filter slowly to find the optimal polarization; avoid forcing the ring if it feels tight. Consider the effect on wide-angle compositions and remove the filter if vignetting appears.
