Papilio 8.5 x 21

Named for the Latin word for butterfly, PENTAX Papilio binoculars are the perfect choice for insect and bird observation in the field or in museums and galleries. Papilio offers a minimum focusing distance of approximately 1.6 feet and incorporates new design technology that automatically compensates for the misalignment of right and left image fields at close ranges. Featuring fully multi-coated optical elements, high-refraction BaK4 glass prisms, a long 15 millimeter eye relief, and protective rubber housing, Papilio is a great choice for spectator sports, hiking and travel as well.
