Bring nature¿s beauty closer than ever. PENTAX Papilio porro-prism binoculars are the perfect choice for close-range butterfly and bird observation. Available in two sizes, the enhanced observation capability of the Papilio binoculars is made possible by a powerful PENTAX Convergent Lens Optical System Engineering (CLOSE) mechanism. Both PENTAX Papilio models also incorporate new design technology that automatically compensates for the misalignment of right and left image fields at close ranges. Named for the Latin word for butterfly, the portable Papilio binoculars are a perfect companion for spectator sports, travel, hiking as well as indoors for observation in museums and galleries.
