Ricoh/Pentax Pentax Spottingscope PF-85EDA KIT + SMC Pentax zoom eyepiece 8-24mm

Pentax Spottingscope PF-85EDA KIT + SMC Pentax 8-24mm – 85mm objective with compact, waterproof design

The Pentax Spottingscope PF-85EDA KIT includes the SMC Pentax zoom eyepiece 8-24mm and pairs a large 85mm objective lens with a compact, lightweight body. It delivers clear, high-contrast views and true-to-life colour rendition, making it well suited for birdwatchers and outdoor enthusiasts who need portable, reliable optics.

Advanced optical design for clear, true-to-life images

The scope uses ED (Extra-low Dispersion) glass elements to reduce chromatic aberration. Additionally, Pentax applies a multi-layer coating to all glass elements to cut reflections. A phase coating on the roof prism further improves contrast and image fidelity. Together, these optics provide a clear image and a high-contrast field of view for observation with accurate colours.

Compact, robust and weatherproof construction

Despite the 85mm objective, the spotting scope remains compact and lightweight for easier transport and field use. A dust-proof glass element in the eyepiece mount creates an airtight assembly, and the body meets waterproof performance equivalent to JIS Class 7. Furthermore, the interior is filled with nitrogen gas to prevent internal fogging during sudden temperature changes, so the view stays clear even in challenging weather.

Eyepiece compatibility and magnification

The eyepiece mount uses a standard 31.7mm (1.25 inch) sleeve. This accepts a variety of eyepieces, including Pentax XF series eyepieces and XW series eyepieces for astronomical observation. The included SMC Pentax zoom eyepiece (8-24mm) yields a magnification range of 20× to 60×. At those magnifications the field of view spans approximately 33 m to 17 m at 1000 m.
