Close-distance observation from a minimum focusing distance of approximately 50 centimeters
In general, observing an object from a close distance with a pair of binoculars causes a discrepancy in the visual field between the right and left eyes. In order to compensate for this discrepancy, the Papilio III WR incorporates the PENTAX-original convergence correction mechanism, which slides the objective lenses in conjunction with the focusing distance. This unique mechanism lets the user more comfortably observe subjects at close range without suffering eye fatigue. Since the objective lenses returns to their original position in long-range observation, this model also performs superbly in normal applications, such as birdwatching, hiking, concerts and sports viewing.
The first Papilio-series model to feature a weather-resistant construction
For the first time in the Papilio series, the Papilio III WR features a weather-resistant construction which minimizes the intrusion of water and moisture into the interior, making it a highly dependable observation tool in the rain and mist and at locations prone to water splashes. An anti-stain coating has also been applied to the eyepieces and front plate-glass surfaces to minimize the adhesion of dust and stains.
Latest HD Coating to further upgrade optical performance
The newest high-performance HD Coating has been applied to some of the optical elements already treated with full multi-coating. Compared with conventional multi-coatings, this assures higher transmittance with less reflection. The result is that the Papilio III WR delivers extra-clear, higher-contrast images even under such demanding conditions as backlighting.
High-performance optical design
All optical elements of the Papilio III WR are treated with a full multi-coating process to assure the optimum imaging performance, while minimizing unwanted reflections. The combination of the aspherical optical elements and the high-refraction BaK4 index glass prisms also delivers a sharp, clear subject image without distortion, even at the edges of the image field.
Easy-to-hold rubber casing
The entire binocular body is encased in a protective rubber casing to assure better holding comfort and superior impact resistance.
Long eye relief
This model’s long 15mm eye relief allows even eyeglass-wearers to clearly and comfortably observe the entire field of vision.
