Professional-grade 10×42 – magnesium body, ED clarity, all-weather performance
The ALPEN OPTICS Chisos 10×42 ED is a full-size binocular built for serious observation. Extra-low dispersion (ED) glass elements virtually eliminate chromatic aberration, delivering sharp, colour-true images from edge to edge. BaK-4 roof prisms benefit from both PXA phase correction coating and HR metallic prism coating with a violet hue, maximising contrast and light transmission. The robust magnesium housing keeps weight down to 610 g while offering superior rigidity and thermal stability compared to polycarbonate. A central focus wheel with two full rotations for the entire range ensures precise focusing, and the 2 m close focus distance opens up macro-level nature observation. Sealed to IPX7 and purged with nitrogen, the Chisos 10×42 shrugs off rain, fog and temperature swings from −10 °C to +50 °C.

True-colour optics in a magnesium chassis – built to last, designed to impress
Extra-low dispersion glass minimises chromatic aberration so colours remain vivid and edges stay crisp at 10× magnification. The PXA phase correction coating combined with HR metallic prism coating on BaK-4 roof prisms delivers exceptional contrast and resolution with a distinctive violet coating hue. An IPX7 waterproof rating combined with nitrogen purging guarantees fog-free, moisture-proof performance from −10 °C to +50 °C, while the magnesium housing provides a strength-to-weight ratio unmatched by plastic alternatives.
Magnesium housing – strength without the weight penalty
Where many binoculars in this class use polycarbonate, the Chisos 10×42 features a magnesium alloy chassis. Magnesium is approximately 33 % lighter than aluminium yet far more rigid than plastic, providing excellent resistance to impacts, temperature changes and mechanical stress. The rubber armouring adds shock absorption and a non-slip grip. At 610 g, the Chisos 10×42 is remarkably light for a full-size 42 mm binocular with a metal body – all-day carry is comfortable even on extended hikes.
2 m close focus & tripod mount – versatility from macro to horizon
A 2 m close focus distance turns the Chisos 10×42 into a macro observation tool, ideal for studying insects, flowers and reptiles at arm’s length. When you need rock-steady views at high magnification – for digiscoping or extended observation sessions – the integrated tripod adapter thread lets you mount the binoculars on any standard tripod. The central focus wheel requires two full rotations to cover the entire range, giving you fine, precise control at every distance.
