Engineered to offer serious viewing capability in a more compact form, the 8x32 Sierra provides superb clarity and brightness, while being small and light enough to accompany you anywhere – from airport terminals to mountain trails.

Lightweight & Travel-Ready

Weighing just 596g and measuring only 128 x 121 x 47mm, the Sierra 8x32 is built for mobility. Whether stashed in a daypack or carried around your neck, it’s the perfect travel companion – robust enough for rugged conditions, yet compact enough for everyday convenience.

All-Weather Performance You Can Rely On

Designed for real-world use, the Sierra 8x32 is waterproof to 1.5 metres for three minutes and fully nitrogen-filled, which prevents internal fogging during sudden temperature changes. The rubber armoured polycarbonate body provides excellent grip and protection against knocks, bumps, and everyday wear.

Whether you’re trekking through humid forests or caught in an unexpected downpour, these binoculars are ready for the challenge.

Crystal Clear Optics

Thanks to Fully Multi-Coated optics and phase-coated BAK-4 roof prisms, the Sierra 8x32 delivers exceptional image brightness, contrast, and colour accuracy – even in lower light conditions. This optical clarity gives you vivid, true-to-life views of your subject, from birds and wildlife to sporting events or distant landscapes.

With a 129m field of view at 1000 metres, you'll capture wide, immersive scenes with ease, all while enjoying steady 8x magnification.

Comfortable, Fast and Precise Viewing

Featuring twist-up metal eyecups with rubber coating, the Sierra 8x32 is equally comfortable for users with or without spectacles. A generous 17.5mm eye relief ensures strain-free viewing, while the centre focus mechanism is smooth and responsive, taking you from close focus (2 metres) to infinity in under a full turn – perfect for tracking fast-moving subjects or adjusting on the fly.
