In strong light, this Zeiss Sunshade protects against dazzling sun rays. Glare and reflexes in bright sunlight are reduced significantly and thus targeting is made a lot easier. The sunshade is lightweight, easy to install and remove. It is installed by threading the sunshade to the riflescope’s objective. The Zeiss 50mm Sunshade is ideal for V4, V5 and LRP S5 Riflescopes.
