A Guide to Birding with Binoculars

By Photo’s Morgan Lyle

Premium glass, a wide field of view, and a close-focus distance of just 6.6′ make the Oberwerk 8×42 Sport ED Binoculars a solid choice for hunters, birders, and outdoor enthusiasts. Antireflection, fully multicoated, extra-low dispersion (ED) glass with dielectric and phase-correcting coatings on the BAK4 prisms deliver bright, sharp, true-color images. The 64.8 apparent field of view presents a generous segment of the horizon and the close-focus distance allows a good look at that nearby butterfly or bird. Designed to stand up to a lifetime of outdoor use, the Sport ED features a lightweight, rubber-armored magnesium chassis and the optical tubes are nitrogen-filled and O-ring sealed to make them waterproof and resistant to internal fogging.

Optical Performance

• 8x power for magnifying the view while preserving a wide exit pupil and long eye relief to make viewing easier and more comfortable
• 42mm objective lenses for gathering the light needed to ensure views remain bright and clear even in challenging light conditions
• Extra-low dispersion (ED) glass elements for reduction of chromatic and spherical aberrations to produce views with true color rendition without halos, diffraction, or distortion across the entire field of view
• BAK4 prisms for delivering a round exit pupil and a crisp and clear image with limited edge distortion
• Dielectric prism coatings for boosting internal surface reflectivity for maximum light transmission through the prism with minimal loss and diffraction and improved contrast and clarity
• Phase-corrected prism coatings for minimizing internal interference to improve contrast, clarity, and resolution
• Antireflection fully multicoated lenses for maximizing light transmission to get bright and clear images with accurate color rendition
• Wide 64.8 apparent angle of view

Use and Handling

• Closed-bridge configuration provides a stable platform for the internal focusing mechanism
• Slip-resistant aluminum center focus wheel is easy to manipulate in cold or wet conditions, or when wearing gloves
• Right-eye diopter adjustment enables users to compensate for optical prescription for sharper views
• Wide 57-74mm interpupillary adjustment range allows easy use by wide variety of people
• Twist-up click-stop eyecups for comfortable use with or without eyewear
• Tripod mountable with optional adapter for hands-free use to eliminate vibrations and arm fatigue
