The Pentax Papilio II 6.5 x 21 are compact, inverted porro-prism U-series binoculars featuring a durable dual-axis, single body design with synchronized IPD adjustment and full multi-coating for better light transmission. Aspherical lens elements give you edge-to-edge sharpness. Fully-multi-coated optics Fully multi-coated lenses serve the essential purpose of maximizing the amount of light passing through a lens, thereby prevent flare and ghosting from interfering with your view. PENTAX applies multiple layers of coatings to every surface of every element and prism in the full Sport Optics lineup. These fully-multi-coated optics assure the maximum light transmission resulting in a clear, crisp viewing. BaK4 prisms Due to its outstanding refractive index, the BaK4 glass prism found in all PENTAX Sport Optics is highly acclaimed for its perfectly round exit pupil and clear, unvignetted image. Aspherical lens elements Edge-to-edge sharpness is a vital element to comfortable viewing. To achieve this, we utilise aspherical lens elements in our eyepieces. This is a specially shaped lens design that reduces aberration to a minimum. 50cm Macro function Absolutely unique and innovative, the macro function of the Papilio allows the user to view objects from a distance of only 50cm! Users can literally immerse themselves in their surroundings rather than watching from a distance. Very popular with entomologists and everyone that loves butterflies, spiders, flowers, etc. Inner focus optics design This sophisticated optical design is critical to low-maintenance and long life guarantee. Exposure to airbourne particles and moisture is avoided, thereby ensuring that no outside influences can penetrate the housing and disrupt functionality. Long eye relief design The long eye relief offered in all PENTAX Sport Optics allows the viewer to see the entire field of view clearly and effortlessly. This is especially beneficial to eyeglass wearers, and allows viewing for extended periods of time without added eye strain.
