Barr & Stroud Sierra 10x32 Binoculars – Compact Power with Rugged Durability

More reach, same portability – perfect for active users who want compact binoculars with extra magnification.

The Barr & Stroud Sierra 10x32 binoculars are designed for those who want the convenience of a compact body combined with powerful 10x magnification. As a step up from the 8x32 model in the Sierra range, these binoculars deliver increased reach for long-distance viewing, while maintaining the same lightweight, travel-friendly size that makes them perfect for hiking, travel, birding, or general outdoor use.

If low-light performance is a priority, you may prefer the larger 10x42 or 10x50 models — but for those seeking versatility, clarity, and compact form, the 10x32 Sierra strikes an outstanding balance.

Compact Design with Extended Reach

Offering 10x magnification and 32mm objective lenses, the Sierra 10x32 provides detailed long-range views while remaining small and light enough to carry comfortably all day. It’s a great option for users who want a more powerful view without the bulk of full-sized binoculars — ideal for tracking distant wildlife, viewing scenery, or attending outdoor events.

Weatherproof and Built to Last

Engineered for outdoor reliability, the Sierra 10x32 is waterproof to 1.5 metres for up to three minutes and fully nitrogen-filled to eliminate internal fogging caused by sudden temperature shifts. The rubber-armoured polycarbonate body is rugged and impact-resistant, offering a secure grip in wet or gloved conditions.

Whether you're trekking through forest trails or facing unexpected rain, these binoculars are built to handle the elements.

Superior Optical Performance

The Sierra range features Fully Multi-Coated lenses and phase-coated BAK-4 roof prisms – a high-quality optical system designed to maximise light transmission and reduce glare. The result is bright, contrast-rich, and colour-accurate images, even in challenging lighting conditions.

With a field of view of 101 metres at 1000 metres, the 10x32 model offers a clear, wide image that's easy to track and focus.

Comfortable, Quick, and Glasses-Friendly

Designed for long viewing sessions, the Sierra 10x32 features twist-up metal eyecups with soft rubber coating and a 14mm eye relief, making them comfortable for glasses wearers. The centre focusing wheel is smooth and precise, with a close focus distance of just 2 metres — perfect for spotting butterflies, plants, or birds at close range.
