A MUST-HAVE - Whether you’re indoors or outdoors, the right polarizing filter is a must for every photography equipment. No other filter provides such a simple and fast method for breathtaking pictures through reduced reflections on water and smooth non-metallic surfaces. Enjoy richer colors in landscape photography, outlining clouds, skies, and skylines in perfect clarity. | EASY TO USE CAMERA FILTER - The Käsemann polarization filter can easily be screwed onto the filter thread of most lenses. Thanks to its special design, the adjustment ring can then be rotated on the filter without resistance in order to improve your images in the simplest possible way. You see an immediate result through the camera viewfinder, or on the display. Adjust the effect strength as desired. | BEST WORKMANSHIP - The High Transmission (HTC) polarization film is set between two elaborately ground and polished cover glasses. It is particularly neutral in color and of high quality, providing for much sharper and richer images than conventional polarizing filters. The MRC glass has been refined with several wafer-thin layers of coating to ensure high scratch resistance and a dirt- and water-repellent effect due to nanotechnology (lotus effect). | TOUGH & SOLID MOUNTS - B+W sockets are absolutely accurate, easy to apply, and easy to adjust as polarizing filters thanks to their nanometer precision manufacturing. With an extra narrow XS-PRO mount, vignettes can be ruled out in most cases, even at high wide-angle angles. Due to the internal thread, a conventional lens hood can also be fitted so you can take better pictures. | MADE IN GERMANY - Schneider Kreuznach (B + W) - We’re proudly your precision mechanics specialists for filters, photography, optics and precision, with more than 100 years of German experience.
