Pentax PF-85EDA 80mm Spotting Scope Black One Size. 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. 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 /3.2ft.) for dependable use even in the rain or mist. This model cannot be used underwater.
