B+W T-Pro Circular Polarizer HTC MRC nano Käsemann 77mm

The B+W T-Pro Circular Polarizer HTC MRC nano Käsemann 77mm is a premium filter designed for photographers who demand the highest image quality. This circular polarizer effectively reduces reflections from non-metallic surfaces, enhances color saturation, and increases contrast, making it ideal for landscape, travel, and outdoor photography. The Käsemann polarizing film ensures high efficiency and neutral color rendition, while the MRC nano coating provides water repellency, scratch resistance, and easy cleaning. The slim brass frame minimizes vignetting, even on wide-angle lenses, and the front thread allows for use of a lens cap or additional filters.

Advantages

This filter offers exceptional light transmission with a filter factor of 2.5-2.8x (approx. 1.3-1.5 stops), ensuring minimal impact on exposure. The multi-resistant coating protects against water, dirt, and scratches, maintaining optical clarity in challenging conditions. The brass frame is durable and prevents filter jamming on lenses. Optimized for wide-angle lenses, it prevents vignetting while maintaining full functionality.
