Newly designed optics incorporate a large-aperture 85mm objective lens, delivering a bright, clear, high-contrast field of view for high-quality observations. ED (Extra-low Dispersion) glass optical elements effectively minimize chromatic aberrations, and the latest multi-layer coating
process drastically reduces reflectance. The roof prism optical design enables the PENTAX PF-85EDA to be compact and highly portable, making it comfortable to carry for outdoor explorations. With a dust-proof glass element
in the eyepiece mount, the scope is waterproof (equivalent to JIS Class 7; with water resistance to a depth of 1m) for dependable use even in the rain or mist. The scope’s interior is filled with nitrogen gas to prevent fogging caused by sudden temperature changes, ensuring a clear field of
view, even in challenging weather conditions Its eyepiece section is slanted upward at a 45-degree angle, enabling the user to easily adjust the eye level and observe subjects while standing or sitting in a natural, relaxed posture. The eyepiece mount’s standard 31.7mm (1.25 inch) sleeve accepts a range of eyepieces including the XF series specifically designed for PENTAX spotting scopes and the XW series optimized for astronomical observation.
