Product Overview

Pentax’s Jupiter 8x40 Binoculars are built for real-world use – from glassing roos on a ridge line to tracking footy plays from the cheap seats. The 8x magnification and bright 40mm objective lenses give you a wide, easy-to-follow view with plenty of detail, so you’re not fighting tunnel vision or dim optics at dusk. Multi-coated glass, a generous 5mm exit pupil and 13mm of eye relief combine for a sharp, comfortable image that stays clear as the light drops.

The porro prism design delivers a strong sense of depth, making it easier to judge distance and pick subjects out of cluttered bush. A tough polycarbonate body wrapped in rubber armour shrugs off knocks and keeps its grip when it’s cold or wet, while the centre focus wheel is large and positive so you can dial in quickly with one hand. With a close-focus of 6 metres and tripod-mount capability, the Jupiter 8x40 is a versatile, no-nonsense bino for birding, hunting, travel and general outdoor use – exactly what you want when you’re out in the paddock, not behind a desk.
