GPO Passion 8x56 Binoculars

The GPO Passion 8x56 (product ID 47032382325043) is a large-objective binocular built specifically for low-light use. The 8x magnification paired with a 56mm objective lens produces a 7mm exit pupil one of the largest available in a handheld binocular. That means noticeably brighter images at dusk and dawn compared to standard 42mm models. The 129m field of view at 1000m gives you a wide, stable image that's easy to hold steady at 8x.

GPO uses a custom Abbe-König prism system rather than the more common roof prism. This design transmits more light without the need for phase correction coatings. Combined with GPO's high-transmission bright lens coatings applied fully across all optical surfaces, you get strong contrast and colour accuracy even in failing light. No ED glass is used but the Abbe-König design compensates well for chromatic aberration.

The body is built from magnesium alloy and weighs 1245g. It is waterproof and measures H67 x W158 x L192mm. Eye relief is 20mm which suits eyeglass wearers well. The 10-year manufacturer warranty backs the build quality.

If you need a serious low-light binocular for wildlife watching at dawn or dusk, the GPO Passion 8x56 delivers a large exit pupil, wide field of view and a proven prism design in a waterproof magnesium body.

The GPO Passion 8x56 uses an Abbe-König prism which is a full-reflection design that transmits more light than a standard roof prism. No phase correction coatings are needed. The 56mm objective paired with 8x magnification gives a 7mm exit pupil a large figure that delivers a bright image in low light. GPO's fully multi-coated bright lens coatings maximise light throughput across all surfaces. The 20mm eye relief and 129m field of view at 1000m make it practical for extended field sessions.

The chassis is magnesium alloy giving a strong and relatively lightweight frame for a 56mm binocular. The body is rubber armoured for grip and protection. Lenses are fully multi-coated optical glass. The Abbe-König prism is a high-transmission glass prism design. No ED glass is used in this model.

Use a lens cloth or brush to clean glass never wipe dry with rough fabric. Store in the case when not in use. Keep the hinge and eyecups free of grit. Store in a dry place. The 10-year warranty requires normal use and proper maintenance so avoid knocks and keep the body clean.
