Leupold BX-5 Santiam HD 8x42

• 8x42 configuration: The 8x magnification gives a steady, easy-to-hold view for scanning large areas, while the 42 mm objective lenses gather enough light for dawn, dusk, and woodland use.
• Twilight Max HD system: Leupold’s light-management system is tuned to improve contrast and control glare, helping fine details stand out when animals blend into shadow or backlit terrain.
• Open-bridge roof prism body: The open-bridge design reduces bulk in the hand and gives a secure grip during long glassing sessions, especially when moving through uneven ground.
• Long 18.50 mm eye relief: Generous eye relief makes the binocular more comfortable over extended use and helps eyeglass wearers see the full field of view more easily.
• Waterproof, fogproof construction: Argon filling and sealed construction keep the optic usable through rain, cold starts, and rapid temperature changes that can fog lesser binoculars internally.

About the Leupold BX-5 Santiam Series

The Leupold BX-5 Santiam series sits in the upper end of Leupold’s hunting binocular range and is built for users who spend long periods behind glass. Introduced with additional 8x42 and 10x42 models for 2018, the line grew around a format that balances field use, carry comfort, and the optical performance needed for locating game at distance. Across the series, Leupold uses its Twilight Max HD light-management system to improve low-light visibility, suppress glare, and maintain useful contrast when conditions are flat or the sun is low.

The series is also defined by its open-bridge design, which keeps handling secure and natural during extended observation, and by Guard-ion hydrophobic lens coating, which helps shed water and dirt from the exterior lens surfaces. Leupold positions the BX-5 Santiam HD as a Professional-Grade optical system, aimed at hunters and outdoorsmen who need a binocular that can move from close timber to open country without becoming tiring to carry or difficult to use for hours at a time. With configurations ranging from compact 42 mm models to higher-magnification options, the series covers everything from general stalking and spot-and-stalk hunting to longer-range glassing from ridgelines and vantage points.

About the Leupold BX-5 Santiam HD 8x42

The Leupold BX-5 Santiam HD 8x42 is the most versatile format in the Santiam family for hunters who want one binocular to cover most field situations. Its 8x magnification keeps the image calm and easy to track when glassing by hand, while the 42.00 mm objective lenses provide enough light-gathering ability for early-morning and late-evening observation without the extra bulk of a larger 50 mm or 56 mm body. That balance makes it especially well suited to woodland edges, broken terrain, and general-purpose hunting optics use where targets may appear close and disappear quickly.

The optical layout combines a Roof - Schmidt/Pechan prism system with Fully Multicoated lenses, helping deliver a bright, contrast-rich image in a compact body. A 126.00 m/1000m field of view gives the user enough width to scan efficiently and relocate moving animals without feeling tunnelled in, while the 5.30 mm exit pupil supports comfortable viewing in dimmer light. The long 18.50 mm eye relief is useful for eyeglass wearers and reduces fatigue during prolonged sessions behind the binocular.

Mechanically, the binocular is built around an open-bridge body with central focusing, so it is easy to carry one-handed and quick to refocus as distances change. The right-eyepiece diopter allows fine adjustment to match the user’s vision, and the short 1.60 m close focus is practical when observing nearby detail as well as distant terrain. With waterproof, fogproof, argon-filled construction in a 670.00 g package, this model is designed to stay manageable on the chest all day while remaining dependable in wet and changeable weather.

About Leupold

Leupold & Volpel was founded in Portland, Oregon, in 1907 by Fred Leupold and Adam Volpel. The company later expanded into sporting optics and introduced its first riflescope, the Plainsman in 1947, establishing the direction that still defines the brand today. Leupold also introduced the Duplex reticle in 1962, a design that became widely recognized in hunting optics.

Today, Leupold & Stevens, Inc. is headquartered in Beaverton, Oregon and remains family-owned. Its product range covers riflescopes, red dot sights, binoculars, spotting scopes, rangefinders, and thermal optics, with a strong focus on hunting, shooting, and outdoor use. That broad experience across sport optics is reflected in products like the BX-5 Santiam HD, where practical field handling and durable construction are given as much attention as optical performance.
