The PF-85EDA spotting scope, with its 85mm ED lens, offers luminous, high-contrast views for birdwatching, nature, and astronomy. Waterproof, fog-proof, and crafted in Japan, it's ready for any adventure.

The PF-85EDA spotting scope, designed with versatility in mind, is suitable for a range of activities including birdwatching, nature observation, and astronomy. This model features newly developed optics with an 85mm objective lens that provides a luminous, sharp, and contrast-rich viewing experience, enhancing the quality of observations. It incorporates ED (Extra-low Dispersion) glass to effectively reduce chromatic aberrations, alongside a modern multi-layer coating technique that significantly lowers reflectance for clearer visuals.

The spotting scope is equipped with a dust-proof element at the eyepiece mount, ensuring its waterproof capabilities (meets JIS Class 7 standards, offering water resistance up to 1 meter or 3.2 feet), making it reliable for use in various weather conditions, including rain or mist. However, it is not designed for underwater use.

Crafted in Japan, the PF-85EDA spotting scope is provided with a protective case, along with caps for the objective lens and eyepiece, ensuring its durability and longevity.

Key features of the PF-85EDA Spotting Scope:

  • Bright and Clear Viewing: Utilizes ED (Extra-low Dispersion) glass to reduce chromatic aberrations, combined with full multi-coating and phase coating for high-contrast observations.
  • Fog-Free with Nitrogen Filling: Nitrogen gas inside prevents internal fogging, ensuring clear visibility in varying temperatures.
  • Compact and Waterproof: Despite its size, the design is compact and portable, featuring a roof prism and a dust-proof glass element for waterproofing (up to 1 meter, not for underwater use).
  • Ergonomic Slanted Barrel: The eyepiece is angled at 45 degrees for comfortable, prolonged observation.
  • Versatile Eyepiece Compatibility: Accepts various eyepieces with a 31.7mm (1.25-inch) sleeve, adaptable for different viewing needs.
  • Enhanced Features: Includes a built-in lens hood for light shielding and lens protection, and a tripod receptacle with click-stop rotation for adjustable eyepiece positioning.
