Blending a warming effect with the versatility of a polarizer, the 55mm LB Warming Circular Polarizer Filter from Singh-Ray is a unique filter featuring a "Lighter, Brighter" design that affords 0.6 stops more brightness than other circular polarizer filters. At its core, this filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. The warming effect then complements the increase in clarity and saturation by providing an even, warm cast to subjects.
This filter is constructed from optical glass for clarity and features a lightweight, durable aluminum alloy filter ring. This ring measures 8.6mm thick and has front threads for stacking additional filters or attaching a lens cap.
