The 77mm Carl ZEISS T* UV Filter from ZEISS is a general use, clear filter that helps to absorb ultraviolet light and reduce the bluish cast of daylight. No additional coloration or contrast effects are provided, rendering a clean and natural appearance.

A 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.

The T* anti-reflective coating helps to reduce reflections on the filter's surface and promote a better light transmission for high quality imagery. The filter ring is designed with a slim profile to allow its use on wide angle lenses, but front filter threads are still available for the use of additional filters.
