Product description

Featuring premium optical components, a wide 60° field of a view, and generous 18mm eye relief for comfortable glassing, the SMC XF 8.5mm Eyepiece is designed for use with Pentax 100mm, 80mm and 65mm spotting scopes. This 8.5mm focal length eyepiece yields 74x magnification with PF-100ED, 61x with PF-80EDA, 59x with PF-80ED, 57x with PR-80EDA, 44x with PR-65EDA, and 46x with PF-65EDA II. Extra-low dispersion lanthanum glass elements provide a balanced image with minimal aberrations, while fully multi-coated air-to-glass surfaces and partially coated laminated surfaces avoid reflection for optimal light transmission. A light-shielding diaphragm further reduces internal reflections for a bright, high-contrast image. The eyepiece is constructed to Japanese Industrial Standard Class 4 for water-resistance. It is not to be used underwater, but will easily withstand light rain or dew. Its diameter is the American standard of 1.25", so it can be used in other spotting scopes or telescopes, and it offers a 30.5mm adapter mounting thread under the removable eyecup.
