Pentax SP 10x50 WP Binoculars

The Pentax 65872 SP 10x50 WP is a full-size Porro prism binocular built for outdoor enthusiasts who need bright, detailed views in changing conditions. Its 10x magnification and 50mm objective lenses suit wildlife observation, landscape scanning and general nature study. The waterproof construction protects the optics during rain or humid environments. Multi-stop twist-up eyecups allow comfortable viewing with or without spectacles.

Optics and handling

Large 50 mm objectives gather maximum light to produce contrast-rich, luminous images at dawn or dusk. Premium multi-layer coatings enhance transmission for crisp, true-to-life colour across the field. A rigid body maintains optical alignment over time for consistent comfort during extended sessions. Centre focus provides quick, precise adjustment while tracking moving subjects.

Field of view constraint

At 1000 m the field of view measures 87 m, which frames wide scenes but limits detail on distant, narrow targets. Buyers who need a wider angle for fast-moving action at close range or higher magnification for extreme distance should consider other configurations.

Questions about this item

How do I set the multi-stop twist-up eyecups for my eyes, and what step is often missed?

Twist each eyecup until it clicks into the stop that matches your eye relief; the step people skip is checking both sides independently so the view stays merged.

What maintenance will the 10x50 WP binocular need over time?

Rinse the 50 mm objective lenses with fresh water after salt or dust exposure, then air-dry; the nitrogen-purged body seals mean no internal cleaning is required.

At what point does the 87 m field of view at 1000 m become the limiting factor during long sessions?

The fixed 87 m width at 1000 m is the first limit you notice when panning across wide scenes, because 10x magnification cannot widen it further.
