The magnification is varied by a wide ring with a crimped surface.The telescope has a built-in 1/4-20 (rotating) port for convenient mounting on a photographic tripod.Be prepared for this image qualityThe optical system uses HD lenses and Twilight Light Max Management HD system for excellent light transmission and stray light reduction (90%).The visible image is crisp and sharp from edge to edge and deep, allowing the telescope to be observed at dawn and dusk (adding approximately 30 minutes of light).The telescope has an impressive twilight factor of 46.5 - 66.3 .All lenses are coated with anti-glare, fully multi-coated lens systems that provide maximum brightness, clarity and color accuracy. They ensure a clear, crystal clear and high contrast image in all conditions throughout the entire field of view.The outer surfaces of the lenses are protected by the highest wear-resistant DiamondCoat 2 coating offered by Leupold.DiamondCoat 2 coating promotes ionization, further increasing light transmission. This affects the brightness, transparency and contrast of the image seen, and allows the binoculars to be used in the harshest conditions on earth.The additional Guard-Ion coating effectively protects the optics from scratches and reduces the deposition of water, dirt and fingerprints.The lenses are military-grade scratch-resistant , guaranteeing durability and excellent condition for many years.AccessoriesA neoprene cover on the barrel provides additional protection for the binoculars during observation and transport.The Leupold SX-5 Santiam 27-55 × 80 HD will work wherever quality and comfort of observation is important, regardless of weather conditions.Impressive brightness, image clarity and a wide magnification range allow the binocular to be used for long-range shooting, wildlife, nature observation, uniform and rescue applications.SPECIFICATIONSFeature Sheet InformationGas Refill NitrogenAngular Field of View [°] 2Linear Field of View at 1000 m [m] 35-24.3Min.
