Bresser Pirsch ED 8x42 Binoculars

The Bresser Pirsch ED 8x42 (product ID 47032162910515) delivers 8x magnification through a 42mm objective lens. That pairing gives you a 5.25mm exit pupil and a 125m field of view at 1000m wide enough for fast-moving wildlife and comfortable for extended use. The 8x42 format is one of the most practical all-round binocular sizes available.

The optics are built around high-performance ED glass that eliminates colour fringing and keeps images sharp edge to edge. Phase-corrected roof prisms sit behind dielectric coatings on the prisms and fully multi-coated lenses throughout. Barium-Kron glass in the prism system pushes brightness further. The result is high contrast and accurate colour even at dusk.

The body is rubber armoured all over for a secure grip and weighs just 636g. Argon gas purging keeps internal fogging at bay and the binoculars are fully waterproof. TwistUp eyecups adjust in two steps with 17.11mm of eye relief workable for spectacle wearers. A wide carrying strap is included.

Lifetime manufacturer warranty backs the Pirsch ED 8x42. ED glass, dielectric prism coatings, phase correction and argon filling at this weight make it a strong performer for birdwatching, wildlife and low-light use.

The Pirsch ED 8x42 uses a roof prism design with Barium-Kron glass and ED extra-low dispersion elements. ED glass reduces chromatic aberration the colour fringing that softens edges. Dielectric coatings on the prisms reflect more light than standard silver coatings. Phase correction coatings fix the wave interference that roof prisms introduce. The 42mm objective divided by 8x magnification gives a 5.25mm exit pupil bright enough for dawn and dusk. Fully multi-coated lenses cut reflection losses at every glass surface.

The chassis uses Barium-Kron optical glass in the prism system alongside ED extra-low dispersion glass elements. The exterior is covered in rubber armouring for grip and impact resistance. Argon gas fills the sealed internal chamber to prevent fogging. No magnesium or polycarbonate chassis details are stated by the manufacturer.

Use a blower brush before wiping lenses with a clean microfibre cloth. Store in the case when not in use and keep the strap attached. Keep the body dry and check the eyecup twist mechanism regularly. Avoid disassembly the lifetime warranty depends on normal careful use only.
