The Hoya 46mm HD2 UV Filter is a general use, clear filter that helps to absorb ultraviolet light. No additional coloration or contrast is provided, allowing you to pair this filter with others.
The UV filter is also useful as a general protective filter to leave on lenses at all times. Filters help to reduce dust and moisture from reaching your lens element and provide additional protection in case of drops or situations where scratching could occur.
Hoya HD2 UV 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.
