Viking Osprey ED 8x25 Compact Binoculars

The Viking Osprey ED 8x25 (product ID 55448717197687) is an 8x magnification compact binocular with a 25mm objective lens. That pairing gives you a 140m field of view at 1000m wide enough for fast-moving subjects. The double hinge design folds down to just W110 x L110 x H40mm so it genuinely fits in a jacket pocket. It weighs only 310g.

The optics use ED glass extra-low dispersion which reduces colour fringing and keeps images sharp across the whole frame. Flat field technology delivers edge-to-edge clarity. The BAK 4 prisms are phase-corrected and dielectric-coated. Full broadband multi-coating on all lenses maximises light transmission for bright clean images even in dull conditions.

The body is magnesium alloy light but solid. Nitrogen filling makes these waterproof and fogproof so internal fogging is not a problem in cold or wet weather. Eye relief is 16.3mm. The central focus wheel is smooth and the build feels secure in hand during extended use.

A 10-year manufacturer warranty backs the whole package. Supplied with a hard clam shell case, strap and rainguard. Rated 4.8/5 from over 2,000 Google reviews. These are serious compact binoculars built for real-world use.

The 8x25 configuration gives a 3.1mm exit pupil fine in daylight. ED glass cuts chromatic aberration so colour fringing is minimal. BAK 4 prisms with dielectric and phase-correction coatings maintain contrast and colour accuracy through the optical path. Full broadband multi-coating on every lens surface reduces reflection and boosts light transmission. Flat field technology keeps the image sharp right to the edges. Nitrogen filling prevents internal condensation when temperatures change.

The chassis is magnesium alloy light and rigid. The body is rubber-armoured for grip and protection. Optics use ED extra-low dispersion glass. BAK 4 roof prisms carry dielectric and phase-correction coatings. All external and internal lens surfaces are fully multi-coated with full broadband coatings.

Use a lens brush or blower before wiping with a microfibre cloth. Store in the supplied hard clam shell case when not in use. Keep dry and avoid knocks to the hinge. The 10-year warranty requires normal careful use avoid dropping and never use abrasive materials on the lenses.
