Why B+W Filter?
Behind the globally recognized B+W filter quality is a continuous process of optimization and quality control which already begins with the raw glass blocks. For the production of the high-precision B+W filters Schott colored glass is used almost exclusively because Schott guarantees the very highest glass quality.
In Bad Kreuznach, computer-controlled grinding and polishing machines produce the highest filter quality from this raw material in an impressive range of designs and diameters. Special production processes remain the domain of the optimizing handcraft of experienced specialists. Strict quality checks in all key production steps ensure seamless production standards. B+W quality does not come about by coincidence, but is clearly defined: to manufacture exactly plane-parallel filter discs without arching or wedge errors (deviating thickness) which could lead to partial image blurring. The filter glass must be completely smooth, because roughness results in scattered light and an unwanted soft focus effect. B+W filter glass meets the highest requirements of camera and lens manufacturers and guarantees optimum imaging quality.
B+W is the first filter manufacturer in the world to offer MRC (Multi Resistant Coating). This multi-layer coating is vapor-deposited in highly advanced vacuum coating plants. It is extremely low-reflective and highly resistant to scratching. But above all its unique dirt and water-repellent surface makes cleaning the filters easier. In this way, filters can also perform a protective function for the front lens. The continuous new development and further development of the B+W filter models and the final inspection of each individual filter mean that users can achieve the best possible photographic results. It is therefore important to give the same consideration to quality when buying a filter as when selecting your lenses. 60 years of know-how guarantee top filter quality to meet global market standards. A brand promise we can be very proud of in Bad Kreuznach.
B+W Protection Filter UV 010
The classic among the protection filters blocks the unwanted UV component contained in daylight. The invisible UV light occurs more in pure sea air and in the mountains, and can lead to blur and blue cast. The colorless UV filters are suitable for both analog and digital cameras and ensure more brilliant pictures. The can remain permanently on the lens to protect it from dirt and damage. A high-grade MRC finish provides optimum reflection reduction.
Active photography demands a great deal of cameras and lenses. It therefore makes sense to protect the sensitive front element of the lens against flying sand, dust, fingerprints and water with a filter. Filters not only cost a fraction of the price of a lens, but are also easier to clean. B+W protection filters can remain permanently in front of the lens as they are absolutely colorless, highly transparent and extremely low-reflective due to their hard MRC finish. The optical information reaches the image sensor (or film) uninfluenced. The filters have no exposure factor. Protection factors play a particularly important role In digital photography. Larger depth of field due to small sensors increases the influence of front lens soiling on image quality. Particularly in zoom lenses with low light intensity, fingerprints have the effect of reducing sharpness considerably.
Frequent cleaning of the front lens, however, can not only cause scratching, but also transport dirt particles or moisture on the edge of the mount into the inside of the lens system.
Multi Resistant Coating with pearl effect
To guarantee perfect image quality, filters must be kept clean. This is supported by the hard MRC finish with its dirt and water-repellent pearl effect coating. This is the best way to clean filters: Never rub off dry, loose dirt particles, but remove them first with compressed air (if possible without touching) or a soft lens brush. Breath on the particle-free filter surface and clean it with a soft cleaning wipes specially for multi-coated lenses. Do not use paper tissues as their fibers cling due to electrostatic charges. Little effort for constantly perfect image quality.
