GPO Passion HD 8x42 Binoculars

The GPO Passion HD 8x42 (product ID 47032384422195) pairs 8x magnification with a 42mm objective lens. That combination gives you a 125m field of view at 1000m and a 5.25mm exit pupil solid for general wildlife watching and low light use. The 19.5mm eye relief makes these comfortable for spectacle wearers. Weight is 850g and dimensions are H56 x W130 x L156mm.

The lenses are multi-coated for sharp optics with good light transmission and colour accuracy. GPO's own PASSION drop water-repellent coating sits on the outer lenses to shed dirt and water. Note that the spec confirms no ED glass is used here. The prism system and multi-coating still deliver strong brightness and contrast in the field.

The body is magnesium alloy durable without being heavy. These are fully waterproof and nitrogen filled for fogproof performance. Rotating eyecups and a central focus wheel with integrated dioptre adjustment make handling straightforward. The micro bridge design keeps things ergonomic during long sessions.

A 10-year manufacturer warranty backs the build. The box includes a carry case and neck strap. For birdwatching and wildlife use these are a well-specified pair at this size.

Nitrogen filling prevents internal condensation. The 125m field of view at 1000m and 19.5mm eye relief make this a practical all-round wildlife and birdwatching instrument.
