The Pentax 10x42 S-Series SD WP binoculars deliver premium optical performance in a rugged, portable design. With 10x magnification and large 42 mm objective lenses, they provide bright, high-contrast images even in low-light conditions. Extra-low dispersion (ED) glass corrects chromatic aberration for accurate colours, while fully multicoated optics maximise light transmission for crisp, clear views.
Featuring ED glass elements and fully antireflective-coated lenses, these binoculars produce sharp, blur-free images with minimal glare. The 10x magnification and 113.2 m field of view at 1000 m allow distant subjects to be observed with ease. A 16 mm eye relief and 4.2 mm exit pupil provide comfortable viewing, while a close-focus distance of 2.7 m enables detailed observation of nearby objects.
The binoculars feature a thermoplastic elastomer resin housing for a secure, non-slip grip. Interpupillary adjustment from 56 to 78 mm, extendable eyepieces, and a smooth centre focus wheel allow effortless operation. Optional TP-3 tripod mounting provides stable, hands-free viewing for longer sessions. Compact dimensions of 5.5 x 5.4 x 2.1 in (14 x 13.7 x 5.3 cm) and 675 g weight make them highly portable.
Nitrogen-filled optical tubes prevent internal fogging, and waterproof construction ensures dependable performance in all conditions. The robust, rubberised housing protects against impacts while providing a secure, comfortable grip.
