This Kase Filter Kit includes a UV filter and a circular polarizer filter. Each filter in this kit can provide one of two enhancements to your imagery while using a Canon EF 500mm f/4L IS II USM Lens. A UV filter adapter ring is also provided, as well as a lens cap, and a filter case that can accommodate both filters, which feature multi-coated Schott B270 Superwhite glass for enhanced clarity and color fidelity. A general-use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight, the UV Filter can be screwed on after the UV filter adapter ring is installed along the front of a compatible lens. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created while using this filter, and adjustments to exposure are not required. The UV filter is also useful as a general protective filter to leave on a Canon EF 500mm f/4L IS II USM Lens at all times. Such filters help to reduce dust and moisture from reaching the front lens element and provide additional protection in case of situations where scratching could occur. The circular polarizer filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. It is made specifically to fit within the accessory filter slot of the Canon EF 500mm f/4L IS II USM Lens. With that lens, the effect of this filter occurs behind the main glass elements instead of in front of them. 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. The circular polarizer filter 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.UV Filter Absorbs UV light and reduces bluish cast of daylightDoes not require adjustments to exposure while in useCreates no additional coloration or contrastGeneral protection filter reduces dust, moisture, and scratches from reaching lens elementsSchott B270 Superwhite glass for enhanced clarity and color fidelityMulti-coated to prevent internal ghosting and reflectionsCircular Polarizer Filter Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surfacePolarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the lightClears up haze in distant landscapes and provides more saturated, vivid colorsStrongest effect when used at a 90 angle from the sunCircular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features2x filter factor reduces exposure by 1 stopSchott B270 Superwhite glass for enhanced clarity and color fidelityMulti-coated to prevent internal ghosting and reflections
