The waterproof Pentax UP 10x21 binoculars use Porro prisms and aspherical lens elements to deliver sharpness across the entire field of view. Fully multi-coated lenses and prisms enhance light transmission, while the dual-axis design synchronizes the interpupillary distance adjustment.
The internal focusing system helps prevent dust and moisture from entering the housing. The minimum focusing distance is 2.8 m.
