The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.\u003cbr\u003e\u003cbr\u003eA circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.\u003cbr\u003e\u003cbr\u003eThis filter is non-coated, has approximately 40% average light transmission, and is designed to provide a polarization effect that is 15 to 20% greater than other Tiffen filters which only provide a linear or circular polarization effect and are not UltraPol filters.\u003cbr\u003e\u003cbr\u003eThe Tiffen 77mm UltraPol Circular Polarizer Filter is constructed from Water White glass for increased clarity as well as color fidelity and features an aluminum-alloy filter ring that can be rotated in order to adjust the intensity of the polarization effect.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHelps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.\u003c\/li\u003e\n\u003cli\u003ePolarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.\u003c\/li\u003e\n\u003cli\u003eClears up haze in distant landscapes and provides more saturated, vivid colors.\u003c\/li\u003e\n\u003cli\u003eOffers a 15 to 20% greater polarization effect than other Tiffen filters which only provide a linear or circular polarization effect and are not UltraPol filters.\u003c\/li\u003e\n\u003cli\u003eStrongest effect when used at a 90° angle from the sun.\u003c\/li\u003e\n\u003cli\u003eCircular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.\u003c\/li\u003e\n\u003cli\u003eNon-coated.\u003c\/li\u003e\n\u003cli\u003eApproximately 40% average light transmission.\u003c\/li\u003e\n\u003cli\u003e4x filter factor reduces exposure by 2 stops.\u003c\/li\u003e\n\u003cli\u003eConstructed from Water White glass for increased optical clarity.\u003c\/li\u003e\n\u003cli\u003eAluminum-alloy filter ring for durability while remaining lightweight.\u003c\/li\u003e\n\u003cli\u003eFilter ring can be rotated to adjust the intensity of the polarization effect.\u003c\/li\u003e\n\u003cli\u003e77mm front filter threads allow for use with other filters.\u003c\/li\u003e\n\u003cli\u003ePlastic filter case for storage and transport. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIn The Box:\u003c\/strong\u003e\u003cbr\u003eTiffen 77mm UltraPol Circular Polarizer Filter\u003c\/p\u003e\n\u003cstyle type=\"text\/css\"\u003e\u003c!--\ntd {border: 1px solid #cccccc;}br {mso-data-placement:same-cell;}\n--\u003e\u003c\/style\u003e","brand":"Tiffen","offers":[{"title":"Default Title","offer_id":41609357033517,"sku":"90855","price":112.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0397\/6167\/4285\/files\/90855_01_Hero.png?v=1692327090","url":"https:\/\/glozerscamera.shop\/products\/tiffen-77-ultrapol-circ-pol","provider":"Glazer's Camera","version":"1.0","type":"link"}
