Description

· This Pentax binocular series is called Papilio, the Latin word for butterfly, because it was specifically developed for close-range observation of butterflies and other insects. The Pentax Binoculars Papilio 6.5 x 21 incorporates a special mechanism that automatically compensates for the misalignment of right and left image fields at close ranges (parallax), allowing easy observation of insects in the field and exhibits at galleries and museums. Thanks to its go-anywhere portability, the Pentax Binoculars Papilio series is also ideal for conventional binocular subjects, including spectator sports, travel and hiking. The Pentax Binoculars Papilio series features multi-coated optical elements to minimize unwanted light reflections for a well-defined subject image. The combination of aspherical optical elements and high-refraction BaK4 glass prisms assures a sharp, clear image with minimal distortion, even at the edges.
