The light from the sun naturally becomes partially polarised due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarising filter arranges, and filters, this directionally polarised 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\u003eA circular polariser only differs from a linear polariser in that it contains a quarter wave plane in addition to the linear polarising filter. The addition of this quarter wave plane is to circularly polarise the linearly polarised light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polariser, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarised, it permits the use of these functions.\u003c\/p\u003e\n \u003cp\u003eThis filter is constructed from optical glass for clarity as well as colour fidelity and features a thin, aluminium-alloy filter ring that can be rotated to adjust the intensity of the polarisation effect. To prevent internal ghosting and reflections, eight layers of anti-reflection multi-coatings are applied to the filter's glass. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.\u003c\/p\u003e\n \u003ch3\u003eKey Features:\u003c\/h3\u003e\n \u003cp\u003eCircular Polariser Filter\u003c\/p\u003e\n \u003cp\u003eFilter Factor, +1 Stop\u003c\/p\u003e\n \u003cp\u003eHelps to Eliminate Reflections and Glare\u003c\/p\u003e\n \u003cp\u003eReduces Haze in Landscapes\u003c\/p\u003e\n \u003cp\u003eGreater Colour and Tonal Saturation\u003c\/p\u003e\n \u003cp\u003eEight-Layer Multi-Coating\u003c\/p\u003e\n \u003cp\u003eOptical Glass Construction\u003c\/p\u003e\n \u003cp\u003eThin, Aluminium-Alloy Filter Ring\u003c\/p\u003e\n \u003ch3\u003eWhat's in the Box:\u003c\/h3\u003e\n \u003cp\u003eHoya HD Circular Polariser Filter\u003c\/p\u003e","brand":"Hoya","offers":[{"title":"40.5 mm","offer_id":46845037445287,"sku":"GC40-C553940","price":167.0,"currency_code":"AUD","in_stock":true},{"title":"52 mm","offer_id":46845037478055,"sku":"GC40-C559352","price":158.99,"currency_code":"AUD","in_stock":true},{"title":"55 mm","offer_id":46845037510823,"sku":"GC40-C553955","price":237.0,"currency_code":"AUD","in_stock":true},{"title":"58 mm","offer_id":46845037543591,"sku":"GC40-C553958","price":273.0,"currency_code":"AUD","in_stock":true},{"title":"62 mm","offer_id":46845037576359,"sku":"GC40-C553962","price":293.0,"currency_code":"AUD","in_stock":true},{"title":"49 mm","offer_id":46853953454247,"sku":"GC40-C553949","price":161.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/4083\/0375\/files\/GC40-C553940.jpg?v=1750137223","url":"https:\/\/www.georges.com.au\/products\/hoya-hd-circular-polariser-filter","provider":"Georges Cameras","version":"1.0","type":"link"}
