Developed to give hunters and birders a slightly higher magnification over standard 8x optics while preserving a wide-angle field of view, long eye relief, and limiting visible hand-shake common in higher power glasses, Swarovski's 8.5x42 EL Binoculars feature a high-transmission optical path, legendary Swarovski optical coatings, and a weather-sealed magnesium-alloy housing that delivers exceptional performance with the ability to withstand extreme conditions.

Optical Performance

• Atypical 8.5x magnification provides a slightly higher-than-normal magnification without sacrificing field of view, eye relief, or exit pupil—ensuring maximum comfort and versatility
• 42mm objective lenses keep the overall form factor small while offering the low-light performance required for hunting, birding, and observing wildlife when many animals are most active
• Compact roof prism optical path ensures the optical tubes are thin for easier handling
• Proprietary SWAROVISION optical system ensures clear views with rich detail, crisp contrast, and accurate color fidelity
• SWAROCLEAN non-stick coatings make cleaning dirt, dust, sap, moisture, and fingerprints from lens surfaces easy and fast
• Wide 60° apparent angle of view presents an immersive observational experience without the need to move your head from side to side to take in the whole scene before you
• Spacious 399-foot field of view at 1000 yards

SWAROVISION Details

• Fluoride glass virtually eliminates chromatic aberration for improved color rendition, resolution, and contrast
• Field-flattener lenses improve edge sharpness and lower the distortion
• Phase-correcting coatings further improve color and contrast
• SWARODUR outer coating on optics helps to prevent scratches and abrasions
• SWAROBRIGHT coatings provide enhanced contrast, brightness, and color fidelity
• SWAROTOP coatings on lenses and prisms reduce light reflection to improve brightness and contrast

Use and Handling

• Open-bridge, dual-hinge configuration provides additional gripping surface area for better handling
• Large slip-resistant center focusing wheel is easy to manipulate in cold and wet weather, or while wearing gloves
• Rapid focusing mechanism allows you to transition from near and far subjects with a quick movement
• ±5 right-eye dioptric correction range enables users to compensate for individual optical prescriptions for tack-sharp images
• Diopter adjustment integrated into the focusing knob locks into the setting and prevents accidental adjustment
• Hypoallergenic twist-up eyecups for comfortable use with or without eyewear
• Wide 56-74mm interpupillary adjustment range allows easy use for a wide variety of people
• Exceptional 20mm eye relief ensures comfortable use with reduced eye strain, especially during long glassing sessions
• 4.9mm exit pupil will completely cover pupils when they are open and fully dilated in low light to ensure the entire scene stays in view without vignetting

Construction

• Bridge design helps to reduce overall weight without sacrificing strength or stability
• Lightweight and durable magnesium-alloy chassis
• Green rubber armor protects against drops and impacts while providing slip-resistant grip
• Wraparound grips and ergonomic thumb rests for comfortable long-duration observation
• Nitrogen filled for fogproof performance, especially when moving through extreme temperature changes and environmental conditions
• O-ring sealed to be submersible to 13'
• Tethered objective lens covers and soft rubber ocular rainguard reduce risk of loss
• Broad -13 to 131°F operating temperature range
• Weighs 29.5 ounces
