Ricoh/Pentax Pentax Spottingscope PF-85EDA

Pentax Spottingscope PF-85EDA – 85mm objective with ED glass for high-contrast viewing

The Pentax PF-85EDA spotting scope features a large 85mm objective lens and delivers clear, high-contrast images. It stays compact and lightweight for easy transport, making it suitable for birdwatchers and outdoor enthusiasts who need good optics in the field.

Advanced optical design

The scope uses ED glass elements to effectively minimize chromatic aberration, so color fringing is reduced for cleaner detail. In addition, Pentax applies a modern multi-layer coating process to all glass elements to cut down reflections and improve light transmission. A phase coating on the roof prism further refines image contrast and sharpness. Together, these optical treatments produce a clear image with a high-contrast field of view and true-to-life color rendition.

Waterproofing and anti-fog features

Pentax engineered the eyepiece mount with a dust-proof glass element to create an airtight assembly. As a result, the spotting scope achieves waterproof performance equivalent to JIS Class 7. For use in changing or harsh weather, the optical tube is also filled with nitrogen gas to prevent internal fogging caused by sudden temperature changes. These features help maintain a clear field of view when conditions turn wet or cold.

Eyepiece mount and compatibility

The eyepiece mount uses a standard 31.7mm (1.25 inches) sleeve, which accepts a variety of eyepieces. This includes Pentax XF series eyepieces specifically designed for their spotting scopes, as well as XW series eyepieces that are well suited for astronomical observation. In short, the PF-85EDA works with all XF and XW Pentax eyepieces.
