The image on the right was\ntaken using a B+W Circular Polarizer. Click for larger view. Highly efficient\nstandard circular polarizing filter for all cameras with beam splitters in the\nlight paths of their TTL exposure meter and with autofocus lenses. Circular\npolarization has the same pictorial effect as linear polarization, but allows\nfor proper exposure metering and\/or autofocus distance settings. B+W\nPolarizers increase color saturation and reduce reflections. The neutral gray\ncolor and plane parallel polarizer material guarantee optimal image results.\nHigh-quality optical glass ensures excellent pictorial quality. The filter\nfactor varies according to how the filter is positioned in relation to the\nsun. Exposure compensation is about two f-stops. Linear and circular\npolarizers both consist of a linear polarizer foil but differ in their\nconstruction in the following way. Modern DSLR cameras have a beam-splitting\nprism that sends part of the incoming light to the meter and part to the\nviewfinder. The effect is that the light entering the meter is partially\npolarized by the beam-splitter. A linear polarizer placed on the lens of such\na system will act as a second polarizer and block light to the meter by a\ndegree dependent on the angle between the prism and the polarizer on the lens.\nThe result is incorrect exposure\/aperture values from the meter. The circular\npolarizer circumvents this problem through the addition of a 1\/4-wave\nretarder, or delay foil. This ensures that the linearly polarized light is\nchanged into a rotation that appears unpolarized to the meter, resulting in\nproper exposure\/aperture readings. MRC - A Special Scratch-Resistant, Water\nand Dirt Repelling Coating The left half of this filter has a traditional\ncoating. The right half has MRC coating. The lens elements of high-quality\nlenses and the plano surfaces of filters require a perfect shape and\nsmoothness to achieve the best optical quality. Dirt, greasy fingerprints,\nwater marks and scratches reduce the image contrast and the sharpness, which\ncan result in blooming at light sources and have an effect similar to a soft-\nfocus lens. A clean front lens element and clean filter surfaces are therefore\nan absolute pre-requisite for demanding photographers. MRC coating causes\nwater to bead up and slide right off. The MRC coating is first and foremost a\nbroadband anti-reflection coating. This means that its reflection-reducing\neffect, which is thus also a transmission-increasing effect, i.e. one which\nsuppresses scattered light and ghost images and transmits more light, has a\nbroadband action over the full spectrum. In contrast, the (almost always blue)\nsingle-layer coating only has a high effect in the medium wavelength range\naround yellow and yellow-green where the eye is most sensitive to light, while\nits effect is greatly reduced toward the blue-violet and purple-red end\nregions of the visible spectrum. With the MRC coating, this blue, violet and\nred to deep-red light cannot produce any contrast reducing scattered light,\nspotty reflections or ghost images. A broadband effect can only be achieved\nwith a multilayer coating which requires a much higher effort and precision\nbecause unevenness and irregularities of the individual layers build up on one\nanother and amplify one another. Schneider therefore uses a plasma-assisted\nevaporation coating process in which inert gas ions accelerated in an\nelectrical field compact the material deposited on the lens surface in the\nvacuum chamber. For photographers, the main advantage of MRC coating, is it's\nability to combat flare and ghosting. An added benefit is that their filters\nremain free of dirt longer, so that they do not have to be cleaned so often.\nWhen cleaning the filter does become necessary, it is a lot easier to wipe off\nthe dirt with a blower brush, because of MRC's ability to repel dirt and\nmoisture. This also reduces the risk of micro-scratches which can occur during\ncleaning. Side view of F-Pro RotatingMount. Click for larger view. F-Pro Brass\nFilter Mount This filter uses a rotating B+W F-Pro filter mount for added\ncreative options. The mount has a front accessory thread and is made of brass.\nCompared to the earlier standard mount, the F-Pro mount, introduced in 2001,\nhas become thinner. Now it can be used with wide angle lenses, including most\n24mm focal lengths on a full frame body, without vignetting. Another advantage\nof the F-Pro mount is its modified retaining ring, which is no longer threaded\nin from the front, but holds the filter glass in place from the back. When\nremoving a filter or lens hood that has been screwed on too tight to the\nfilter, the retaining ring is not at risk of loosening.\u003c\/p\u003e \n\n\n \u003cul class=\"a\"\u003e\n \u003cli\u003eBrass Ring for higher Quality Image\u003c\/li\u003e\n \u003cli\u003eHighest possible polishiing technique\u003c\/li\u003e\n \u003cli\u003eWorld's best optical glass\u003c\/li\u003e\n \u003cli\u003eNew thinner Pro mount.
