They offer the same superior viewing quality as their larger S-series counterparts, thanks to the application of advanced coatings. Despite their compact size, these binoculars do not compromise on optical performance, making them a portable and durable choice for users seeking mobility convenience.The binoculars boast new fully multi-coated lenses, phase correction, BaK4 prism, and an enhanced light transmission coating. These features work together to provide sharp, high-contrast images.
