The Hoya 37mm HD2 Protector Filter is a general use, clear filter that protects the front element of your lens against scratches, dirt, sand, dust, other debris, and moisture. It also provides additional protection in case of drops. The filter can be left on your lens at all times.
Hoya HD2 filters are multi-coated for reducing flare, ghosting, and reflections on the filter surface. As a result, a very high light transmission of 99.35% is possible, providing you with additional contrast and high color fidelity.
The HD2 filters are constructed from optical glass and feature a thin frame. They are backed by a lifetime limited warranty.
