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.\u003c\/p\u003e\n\u003cp class=\"mText\"\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.\u003c\/p\u003e\n\u003cp class=\"mText\"\u003eThis filter is constructed from optical glass for 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. To prevent internal ghosting and reflections, the glass includes 10 layers of anti-reflection coating. These coatings also offer greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters.\u003c\/p\u003e\n\u003cbr\u003e\n\u003ch2 class=\"h2Lit\"\u003eKey Features of Haida PROII Multi-Coating C-POL Filter 72mm\u003c\/h2\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\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\u003e2.5x filter factor reduces exposure by 1.3 stops.\u003c\/li\u003e\n\u003cli\u003eMulti-coated to prevent internal ghosting and reflections.\u003c\/li\u003e\n\u003cli\u003eThin, aluminum-alloy filter ring helps to prevent vignetting while remaining durable and lightweight.\u003c\/li\u003e\n\u003cli\u003eFilter ring can be rotated to adjust the intensity of the polarization effect.\u003c\/li\u003e\n\u003cli\u003e72mm front filter threads allow for use with other filters.\u003c\/li\u003e\n\u003cli\u003eTop knurling to provide a more textured grip when mounting or removing it from a lens.\u003c\/li\u003e\n\u003cli\u003eConstructed from optical glass for clarity and color fidelity.\u003c\/li\u003e\n\u003cli\u003ePlastic filter case for storage and transport.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003cul class=\"mpn\"\u003e\n\u003cli\u003eMPN - HD202077\u003c\/li\u003e\n\u003cli\u003eGTIN - 6900574930779\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Haida","offers":[{"title":"Default Title","offer_id":47111347536057,"sku":"134824","price":89.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/8897\/7337\/files\/haida_77mm_slim_pro_ii_circular_polarizer_filter-1_1_2.jpg?v=1778108108","url":"https:\/\/www.digidirect.com.au\/products\/haida-proii-multi-coating-c-pol-filter-72mm","provider":"digiDirect","version":"1.0","type":"link"}
