- Effortless Close-Range Observation
The Papilio series features the PENTAX-developed Convergent Lens Optical System Engineering mechanism, which automatically slides the left and right objective lenses toward the center when the focus is fixed at a short distance. As a result, the right and left image fields are correctly aligned to facilitate close-range viewing. Thanks to its go-anywhere portability, this new series is also ideal for conventional binocular subjects, including spectator sports, travel and hiking.
- Extra-Short Minimum Focusing Distance
The Papilio series offers a minimum focusing distance of just 50 centimeters (approx. 1.6 feet), considerably shorter than the two-meter distance (approx. 6.5 feet) offered by similar PENTAX models currently on the market.
- Outstanding Optical Performance
The 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.
- Long Eye Relief
The Papilio series offers a long 15-millimeter eye relief to assure effortless viewing of the entire image field, even for eyeglass wearers.
- Protective Rubber Housing
The protective rubber housing not only protects inner mechanism from external shock, but also assures a firm, comfortable grip of the binocular body even in the field.
