It is made specifically to fit within the accessory filter slot of the Sony FE 400mm f\/2.8 GM OSS Lens, whose front diameter is too large to accommodate a screw-on filter. With that lens, the effect of this filter occurs behind the main glass elements instead of in front of them.\u003c\/p\u003e\n\u003cp class=\"mText\"\u003eThe 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 autofocus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, autofocus 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 and includes an integrated locking mechanism to secure it within the compatible lens, as well as an external dial to allow rotation of the filter glass for control of the polarization effect.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2 class=\"h2Lit\"\u003eKey Features of the Sony Drop-in Circular Polarizer for SEL400F28GM\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with Sony FE 400mm f\/2.8 GM OSS Lens\u003c\/li\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 perpendicular 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 colours\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\u003eConstructed from optical glass for clarity\u003c\/li\u003e\n\u003cli\u003ePlastic filter case for storage and transport\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul class=\"mpn\"\u003e\n\u003cli\u003eMPN - VF-DCPL1\u003c\/li\u003e\n\u003cli\u003eGTIN - 027242913998\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sony","offers":[{"title":"Default Title","offer_id":46839002824889,"sku":"138422","price":599.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/8897\/7337\/files\/sony_drop-in_circular_polarizer_for_sel400f28gm_lens_01.jpg?v=1775374819","url":"https:\/\/www.digidirect.com.au\/products\/sony-drop-in-circular-polarizer-for-sel400f28gm","provider":"digiDirect","version":"1.0","type":"link"}
