Leica E55 UV/IR Filter
The Leica UVA/IR Glass Filter is specifically recommended for the Leica Digital M8 camera. In order to maintain maximum optical clarity, the M8 - with its superior sensor - was not designed with a total IR protection filter system.
This filter is designed to eliminate tints that certain black synthetic items might be subjected to when shooting under certain lighting conditions, such as that of incandescent bulbs. This filter can also serve to help protect the glass in your lens.
