Nikon's Action EX
- Extreme All Terrain Binoculars
- are designed to appeal to optics users who value tough construction & reliable optical performance under even the most extreme conditions. Nikon Extreme binoculars feature an all-metal chassis with lens fittings housed in a tough, lightweight polycarbonate body shell. Like all Nikon All Terrain Binoculars, the EX is nitrogen-filled & O-ring sealed for total waterproof, fogproof & shockproof performance in any environment. The binocular bodies are ergonomically shaped, tripod adaptable & rubber coated for a non-slip grip, whether wet or dry. The series features a unique, click-stop eyecup design that not only delivers long eye relief, but also allows for variable eye relief that is customizable to the user's own eyes & eyeglasses. The binoculars are central focus with a diopter control to correct for normal right/left eye vision imbalance.
