Designed for high-quality, high-precision outdoor viewing. The PENTAX PF-65EDA incorporates porro-prism optics and a 65mm objective lens with PENTAX-exclusive ED (Extra-low Dispersion) optical elements to deliver sharp, high-contrast images with minimal chromatic aberration. With a 45-degree slanted lens barrel, the PF-65EDA offers hours of comfortable, fatigue-free viewing. This spotting scope also feature a compact, lightweight body with nitrogen-filled waterproof construction (JIS Class 6), a collet-type eyepiece receptacle for an American-standard 31.7mm (1.25 inch) sleeve, a protective rubber housing, and accessible reach by either hand. When mounted on a tripod, the lens barrel can be twisted 90 degrees clockwise or counterclockwise from thedefault position at top or 180 degrees from side to side along with easy-to-locate pointers at top and 45-degree angles, to assure the best viewing position. The extendible rubber lens hood comes with a sight line to facilitate target-line adjustment. To optimize the performance of these new spotting scopes, PENTAX has developed three compact, high-performance XF-series eyepieces, all featuring a bright, high-contrast image, an American-standard 31.7mm sleeve and focal lengths ideal for outdoor viewing and bird watching.

The PF-100ED is the first fully waterproof and fog-proof 100mm objective spotting scope in the market. The straight-line optical barrel design of the PF-100ED makes it easy for the user to locate a subject quickly. It is housed in a lightweight magnesium-allow body and features time-proven porro-prism optics incorporating ED (Extra-low Dispersion) Lanthanum Crown (rare earth) glass elements to produce sharp, clear images with minimal chromatic aberration. PF-100ED also utilizes Pentax telescope eyepieces renowned for their sharpness, field of view, contrast and freedom from aberration. Used together, you have a world class-viewing instrument.
The Pentax PF-100ED is housed in an exceptionally lightweight magnesium-alloy body.
