Bright, clear field of view
The PENTAX PF-85EDA features ED (Extra-low Dispersion) glass optical elements to effectively minimize chromatic aberrations, and the latest multi-layer coating process to drastically reduce reflectance.
Full multi-coating
With the combination of a full multi-coating process applied to all optical elements and a phase coating process applied to the roof prism, this spotting scope delivers a clear, high-contrast field of view for high-quality observations.
Compact body for excellent portability
Despite its large, 85mm-diameter objective lens, this spotting scope is designed to be compact and highly portable, thanks to the incorporation of the latest optical design featuring a roof prism.
Compatibility with a range of eyepieces
The eyepiece mount features an American-standard 31.7mm (1.25-inch) sleeve to accept a range of eyepieces, including the XF series specifically designed for PENTAX spotting scopes, and the XW series perfect for astronomical observation.
Slanted-barrel design
The eyepiece section is slanted upward at a 45-degree angle, allowing the user to easily adjust the eye level and observe subjects while standing or sitting in a natural, relaxed posture.
Waterproof construction* for use in a rain
By inserting a dust-proof glass element in the eyepiece mount, the spotting scope is designed to be airtight for outstanding waterproof performance (equivalent to JIS Class 7; with water resistance to a depth of one meter*) for dependable use even in the rain or mist. * This model cannot be used underwater.
Nitrogen-filled body for a clear field of view without fogging
The interior of this spotting scope is filled with nitrogen gas to prevent fogging caused by sudden temperature changes, assuring a clear field of view even in demanding weather conditions.
