Pentax 10x25 A-Series AD WP Compact Binoculars

Designed for the nature enthusiast who wants to travel light without compromising image quality, the Pentax 10x25 A-Series AD WP Compact Binoculars provide bright, clear views while weighing only 300.5 g. Their ultra-compact asymmetrical hinge design allows them to fold significantly smaller than standard centre-hinged binoculars, making them ideal for pockets, daypacks, and travel.

Optical Performance

These binoculars offer 10× magnification with 25 mm objective lenses, using phase-corrected BAK4 roof prisms to enhance contrast and deliver accurate colour. Fully multi-coated, anti-reflection optics maximise light transmission for bright, sharp views. With a 5° angle of view and a field of view of 87.5 m at 1000 m, they offer excellent performance in a compact form.

Use and Handling

The closed-bridge design provides a stable grip, while the knurled centre focusing wheel offers smooth, precise control. Twist-up eyecups make them suitable for both spectacle wearers and non-spectacle users. A 20 mm eye relief and 2.5 mm exit pupil ensure comfortable viewing, and the minimum focus distance of 3 m is ideal for observing nearby subjects.

Durable Construction

Built with a lightweight, corrosion- and impact-resistant fibreglass-reinforced polycarbonate housing, these binoculars are designed to withstand demanding outdoor conditions. Nitrogen-filled and O-ring sealed, they are fogproof and submersible to 1 m, remaining reliable in all weather. Rubberised armouring offers added protection and a secure, slip-resistant grip. Compact dimensions of 10.9 × 10.4 × 4.1 cm make them easy to carry anywhere.
