Steiner M1580 15x80mm Floating Prism Binoculars OD Green Makrolon

The Steiner M1580 15x80mm binoculars deliver exceptional long-range observation capabilities with floating prism technology that maintains perfect optical alignment under extreme conditions. Military-grade construction meets precision German optics engineering for professionals who demand unwavering performance in critical situations.

What Makes This Different

Steiner's floating prism system eliminates the mechanical stress that degrades image quality in conventional binoculars over time. The 80mm objective lenses gather 40% more light than standard 70mm models, extending usable observation time into dawn and dusk hours. Sports-Auto Focus technology maintains sharp images from 20 yards to infinity without constant adjustment, a significant advantage over traditional focusing mechanisms that require frequent recalibration.

Key Features

• 15x magnification with 80mm objective lenses for maximum light gathering
• Floating prism system maintains optical alignment under shock and vibration
• Sports-Auto Focus technology eliminates need for constant refocusing
• OD Green Makrolon housing with rubber armor coating resists impact damage
• Waterproof and fog-proof construction rated for extreme weather conditions
• Individual eyepiece adjustment accommodates vision differences
• Tripod adaptable for extended observation sessions

Field performance characteristics include a 4.3-degree field of view at 1000 yards, providing adequate coverage for surveillance and wildlife observation while maintaining the detail resolution needed for target identification. The 5.3mm exit pupil ensures bright images even in low-light conditions. Weather sealing prevents moisture infiltration during extended outdoor use, while the rubber armor coating provides secure grip in wet conditions and absorbs impact shock.
