Filters are made from glass and are very fragile. Handle with appropriate care.
The filters arrive in matched pairs. They should be mounted identically with the larger dimension horizontal.
Polarizing filters generate much heat. High temperatures accelerate filter aging. Therefore, it is recommended to allow enough distance between the filter and the lens so that the beam illuminates at least half of the filter area.
Advisol filters are designed for service of thousands of hours. However, the actual lifetime depends on video content and environmental conditions.
