Leica E82 circular polarizer for lenses with an 82mm filter thread size. Leica’s new line of circular polarizing filters are designed to eliminate undesirable reflections from shiny surfaces like water or glass and help to enhance color contrast without impacting image quality. Do note that depending on how the polarizer is set, there will be some degree of “filter factor” that reduces the amount of light coming through the lens, necessitating some exposure adjustment if working in manual mode. They are manufactured to the same optical standards and with the same aluminum used in Leica M lenses.
The filters are multi-coated high grade optical glass to reduce internal reflections, and are lighter than their predecessors thanks to aluminum versus brass construction. Each filter includes a 2 year Leica warranty and protective plastic case.
