Danubia Bussard I 8x56

• 8x56 low-light configuration: The combination of 8x magnification and a 56.00 mm objective keeps the image bright and steady, which is especially useful for hunting optics and nature observation at dawn, dusk, and in woodland shade.
• Large 7.00 mm exit pupil: A generous exit pupil helps the binocular remain easy to align behind the eyes and supports comfortable viewing in poor light, where quick target acquisition matters.
• Long 23.00 mm eye relief: The extended eye relief improves comfort during long observation sessions and gives eyeglass wearers more usable field of view without feeling cramped behind the eyepieces.
• Roof prism design with fully multicoated optics: The Schmidt/Pechan prism system keeps the body slimmer than a comparable Porro design, while the Fully Multicoated lenses help maintain contrast and light transmission in difficult conditions.
• Nitrogen-filled waterproof housing: Waterproof and fogproof construction helps the binocular stay reliable when moving between cold and warm environments or working in wet weather.

About the Danubia Bussard I Series

The Danubia Bussard I series sits in DÖRR’s Danubia optics range as a practical line of roof-prism binoculars for sport, outdoor use, hunting, and nature observation. A DÖRR catalog published in 2015 already included the BUSSARD I family, showing it as a broad series rather than a single format, with compact pocket binoculars as well as larger roof-prism models for more demanding observation. That spread gives the series a clear role: compact versions for portability and larger variants for brightness and longer sessions in the field.

Across the range, the design emphasis is on nitrogen-filled construction, pressure-water resistance to 1 m, and optical features such as multi-coated lenses and BAK-4 prisms. In practical use, that means the Bussard I line is built around dependable outdoor handling rather than specialist complexity. The series is aimed at users who want straightforward binoculars with modern roof-prism proportions, weather resistance, and solid low-light behavior, whether the binocular is being carried for general nature observation or chosen specifically as hunting binoculars for early-morning and late-evening use.

About the Danubia Bussard I 8x56

The Danubia Bussard I 8x56 is the low-light specialist in the series. Its 8.00 x magnification is easy to hold steadily by hand, while the 56.00 mm objective lenses gather enough light to make the binocular well suited to dusk observation, woodland edges, and other situations where brightness matters more than extra reach. The resulting 7.00 mm exit pupil supports a relaxed view and makes eye placement less critical, which is useful when scanning for movement in fading light.

The optical layout uses Roof - Schmidt/Pechan prisms in a single-hinge body, giving the binocular a more streamlined shape than a traditional Porro design. Fully Multicoated lenses and stated light transmission of >87% help preserve contrast and image brightness, while the 114.28 m/1000m field of view is wide enough for general wildlife observation without making the image feel overly narrow. A 23.00 mm eye relief and twist-up eyecups make the binocular easier to use with or without glasses, and the right-eyepiece diopter adjustment allows the image to be tuned to the user’s eyesight.

For field use, the housing is nitrogen filled, waterproof, and fogproof, so it is better prepared for rain, cold mornings, and temperature changes. The central focusing system keeps operation simple, and the 2.50 m close focus is short enough for nearby observation as well as longer-distance scanning. At 1200.00 g, it is a substantial binocular, but that weight suits its role as a stable, bright 8x56 for hide use, high seats, and deliberate observation in poor light.

About Dorr

Dörr GmbH was founded in 1973 and is based in Neu-Ulm, Bavaria, Germany. The company works as an international importer and exporter and sells products both under its own DÖRR brand and from other brands. Within optics, its range includes binoculars, spotting scopes, and telescopes, giving it a broad presence in observation equipment rather than a single-category focus.

For sport optics, DÖRR uses the Danubia name for its optical products. That is relevant here because the Danubia line covers practical field optics intended for outdoor use, including binoculars designed for hunting and nature observation. The company’s background in distributing and marketing a wide product range is reflected in products such as the Bussard I, which focus on proven configurations, straightforward operation, and weather-resistant construction.
