The Zeiss 55mm Carl Zeiss T* UV Filter facilitates daylight photography by reducing the impact of ultraviolet rays on the lens. This filter can be attached to 55mm-threaded lenses. The UV filter also reduces the bluish cast in images. Moreover, the natural density of the filter doesn't cause any change in coloration of the original image. A T* anti-reflective coating is applied on the filter for minimizing internal reflections. The filter also protects the front lens element from dust, moisture, and scratches.
