HOYA 52mm HD

UV filters belong to a category of photo filters that are suitable for day-to-day use, which means that there's no need to remove them from the lens, not ever. UV filters help you to achieve a higher image clarity and a more accurate colour balance. Another of their many advantages is that they make the lens more resistant to mechanical damage, such as scratches are.
The HD series of filters features high-density sharp cut UV optical glass that has been chemically enhanced. HD glass is 4 x stronger than regular optical glass.
