BW Ksemann circular polarizers are manufactured with a polarizing foil of extremely strict & exacting specifications. In terms of color neutrality & extinction capability the foil quality is ideal. Furthermore the glass used for this filter is sanded & fine-polished for excellent optical quality & the advanced cementing technique prevents delamination in environments of high humidity. This filter does not impair the image sharpness of high-quality photographic lenses which is particularly important in high-resolution digital cameras & aspherical tele lenses. BW MRC nano Nanotechnology with Lotus Effect. Both sides of the BW MRC nano coated filters feature the same high-quality MC layer with 7 layers that is used in the MRC coating. This ensures high transmittance & maximum elimination of reflections by minimising reflection losses. Because the normal 4 reflection losses at the surface of the glass are reduced to an average of well below 0. 5 with an MC layer brighter colors & higher contrasts can be achieved. The MRC nano outer layer is an innovative extra layer that significantly outperforms the dirt- & water-repellent effect of the well-known BW MRC coating. Thanks to the nanotechnology-based surface property lotus effect dirt can hardly adhere. Water experiences a very efficient beading effect & virtually rolls off the surface of the glass. Cleaning the filter is incredibly easy & fast. In addition the superhydrophobic surface reduces fogging. After moving from cold to warm surroundings the condensation disappears from the surface of the filter glass within seconds. Why BW over other filter brands. BW filters have been made with Schott glass which guarantees the very highest glass quality. Good quality cameras & lenses are a major investment & at BW we believe that if you should have the best quality filters. Theres no point in buying an expensive optically superior lens only to put a piece of inferior glass over the front of it BW filters are ...

The BW 82mm XS-Pro Digital ND Vario MRC nano Filter is a solid variable neutral density filter providing an exposure reduction of 1 to 5 stops. The 0. 3 to 1. 5 density creates a darkening of the entire image allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring allowing you to previsualize the additional exposure length required. By slowing your exposure time or increasing your aperture you are able to control depth of field & convey movement more easily. For easier repeatable control over density settings the front ring is also visually demarcated with dots that represent different density values. The Multi-Resistant Coating MRC is both an anti-reflection coating as well as a protective surface. It helps to increase light transmission by reducing reflections scattered light & ghosting. in addition it offers greater protection to the filter substrate & stays cleaner for longer than uncoated filters. The nano coating associated with XS-Pro filters incorporates an additional 8th layer over the regular MRC & results in a better beading effect with water for greater cleaning efficiency. BW filters are constructed from high quality Schott glass for increased optical clarity & color fidelity. This filter features a thin oversized mount which helps to reduce the likelihood to vignetting when used with wide-angle lenses. The filter ring is made from brass for durability as well as jamming prevention. ...

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 & 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 Ksemann High Transmission HTC polarizing filters is fitted with a new polarizing foil which has higher translucency transmission. The BW filter XS-Pro is coated with MRC nano & F-Pro with MRC coating. Why BW over other filter brands. BW filters have been made with Schott glass which guarantees the very highest glass quality. Good quality cameras & lenses are a major investment & at BW we believe that if you should have the best quality filters. Theres no point in buying an expensive optically superior lens only to put a piece of inferior glass over the front of it BW filters are also coated with state of the art coatings BW are the first filter manufacturer in the world to offer multi resistant coatings MRC. The coatings are extremely low-reflective & highly resistant to scratching but above all the unique dirt & water-repellent surface makes cleaning the filters easier. BW filters all feature brass mounts designed to fix the high-quality filter glass in position for life. Brass mounts wont bind with your lens thread or other filters a major advantage over cheaper filters. ...

BW EXAKTA UV Protection Filter MC 49mm Description. All objects reflect ambient light Shiny surfaces reflect strongly & directionally matte weaker & diffuse. By means of this light the intrinsic colors of the objects are superimposed by a milky veil. Since the veil is largely polarized
- especially when exposed to the sun the most beautiful light & shadow effect you can easily prevent the resulting color pollen An Exakta filter Circular rotated on the lens of the camera in its optimal position Pol blocks the polarized light the colors light up again for splendid life-spraying pictures The optimum filter rotation position can be seen in SLR cameras in the viewfinder For other cameras simply rotate the filter in front of the eye & then place it in the position determined on the lens. In addition the Circular Pol filter can also selectively weaken or intensify reflections in the case of oblique incidence of light on shiny glass plastic lacquer or water surfaces
