Product Code: 9337840C

Description

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

For this high-end polarizing filter the foil pieces are selected individually for maximum color neutrality. Following cementing between high-grade optical glass, additional grinding and polishing takes place. This guarantees outstanding sharpness even with very bright, apochromatic lenses. The latest cementing technique ensures lasting stability even in damp climates. The new generation of Käsemann High Transmission (HTC) polarizing filters is fitted with a new polarizing foil which has higher translucency (transmission), yet still provides outstanding effectiveness. The filter extension factor is only 2 to 3, equivalent to approx. 1 to 1.5 f-stops. Available in the F-Pro filter mount exclusively with MRC; in the XS-Pro mount exclusively with MRC nano.

Radiant white clouds against a deep blue sky or saturated fall colors are no coincidence. Polarizing filters (pol filters for short) block the bluish gray veil from the diffusely polarized light of the sky. They augment the purity of true colors and increase color saturation. Polarizing filters are amongst the most important filters in (digital) photography. They can be rotated in the mount, allowing the visible regulation of the elimination effect in the viewfinder or on the display. The filter factor of a polarizing filter is approx. between 4 and 8, equivalent to nearly three f-stops. With the High Transmission Käsemann HTC polarizing filter the filter factor is approx. 2 to 3, which is equivalent to approx. 1 to 1.5 f-stops. The maximum effect is achieved at a shooting angle of 90° to the sun. For an even effect in the picture, 35 mm (or 28 mm in 35 mm film format) should be the minimum. The second beneficial effect of pol filters is the reduction of reflections on non-metallic surfaces (water, shop windows, lacquer). Objects behind these surfaces, including writing behind reflecting lacquer, are made visible – a fascinating way to enhance images without using photo editing.
