Design and Build
The Pentax Papilio II 6.5×21 Binoculars represent a significant advancement in the field of optical engineering, particularly for those with a keen interest in the details of the natural world. This section delves into the meticulous design and build of these binoculars, highlighting their unique features and the thoughtful considerations behind their construction.
Reverse Porro Prism Design
At the heart of the Papilio II’s exceptional close-focus ability is its reverse Porro prism design, which is less common in the compact binocular market. This design choice not only facilitates the remarkable close viewing capabilities but also contributes to the binoculars’ compact form factor. The reverse Porro system, combined with patented converging objectives, allows users to observe details as close as 18 inches away, making it an ideal tool for studying insects, plants, and even artworks with unparalleled clarity.
Durable Construction
Despite their lightweight profile, weighing in at just 290 grams, the Papilio II binoculars are built to last. The main body is constructed from high-quality materials that strike a perfect balance between durability and portability. The outer casing is covered with textured rubber armor, providing a secure grip and added protection against bumps or drops, enhancing the binoculars’ longevity.
Ergonomic Features
Understanding the varied needs of outdoor enthusiasts and nature observers, Pentax has integrated several ergonomic features into the Papilio II design. The binoculars are equipped with a large, textured central focus wheel that is easy to operate, even with gloves on. This focus wheel requires about three full rotations to transition from the minimum focus distance to infinity, allowing for precise adjustments.
The dioptre adjustment, equipped with click stops, is another user-friendly feature that enables users to fine-tune the focus to their eyesight, ensuring sharp images every time. The eyecups are designed to be comfortable against the eyes and adjustable to three positions, catering to eyeglass wearers and those without, with a maximum eye relief of 15mm.
Optical Housing and Protection
Pentax has taken care to ensure that the optical components are well-protected, housing the objectives behind optically flat glass windows. These windows are treated with anti-reflective coatings to maximize light transmission and minimize glare, a particularly beneficial feature in bright, outdoor environments. Although the Papilio II binoculars are not nitrogen-purged or waterproof, their construction quality and the inclusion of a rain guard for the ocular lenses mitigate potential damage from external elements.
Portability and Convenience
With dimensions of 11.0 x 11.4 cm (W/H), the Papilio II is designed for easy handling and transport. Its compact size and light weight make it an ideal companion for hikes, nature walks, or any outdoor adventure where space and weight are considerations. The addition of a tripod mountable feature further extends its versatility, allowing for hands-free observation over extended periods.
Optical Performance
The Pentax Papilio II 6.5×21 Binoculars are distinguished by their exceptional optical performance, tailored to deliver an immersive viewing experience, especially for close-up observations. Central to their design is a unique set of features that enhance both the quality and versatility of the visuals they provide.
Fully Multi-Coated Optics
Every lens surface within the Papilio II is fully multi-coated, a crucial detail that significantly improves light transmission. This treatment reduces reflective losses and ensures that images appear brighter and more vibrant, with enhanced contrast. This feature is particularly beneficial under the varied lighting conditions encountered in outdoor environments, from the shadowed underbrush of forests to sunlit clearings.
Reverse Porro Prism Design
The reverse Porro prism design of the Papilio II contributes to its compact form factor while maintaining a wide field of view. This design is less common than the roof prism setup found in many modern binoculars but offers several advantages, including a greater depth of field and a more three-dimensional image perception. This is especially useful for close-up observations, where understanding the spatial relationship between different elements in the view can enhance the overall experience.
Close Focus Capability
Perhaps the most remarkable feature of the Pentax Papilio II is its close focus capability, allowing users to focus on objects as near as 18 inches (approximately 0.5 meters). This feature is unparalleled in the binocular market and opens up a new realm of possibilities for observation, making these binoculars ideal for studying insects, plants, and even fine details of artworks or textiles.
Exit Pupil and Eye Relief
The exit pupil of 3.23mm, calculated by dividing the objective lens diameter by the magnification, strikes a balance that suits a wide range of lighting conditions. The 15mm eye relief provides a comfortable viewing distance for most users, including those who wear glasses, ensuring that they can also enjoy the full field of view without vignetting.
Field of View
With a field of view of 7.5 degrees (132m at 1000m/323ft at 1000 yards), the Papilio II offers a broad vista that is particularly beneficial when observing larger areas or tracking moving subjects. This wide field of view, combined with the binoculars’ stellar close-focus performance, makes them exceptionally versatile, catering to a broad spectrum of observational hobbies and professional uses.
- Fully-multi-coated optics assure maximum light transmission resulting in high quality viewing. Every surface of every element is fully coated minimizing internal glare and flare and giving a bright clear view.
- Unique Uni-body design enhances durability by locking objective lenses in a single housing and synchronizing the eyepiece movement. This minimizes moving parts and assures these binoculars will function properly and clearly for years to come.
- Aspherical lens elements, which are critical in compact binoculars, provide exceptional edge-to-edge sharpness. This assures that items on the edge of your field of view are just as sharp as those in the center.
- The UP models are offered in unique, attractive color options that match your personal style.
