Leica 40097 12x50 Ultravid HD-Plus Binoculars

The Leica 40097 Ultravid 12x50 HD-Plus binoculars represent the pinnacle of Leica's portable optics engineering. The optical path is built around SCHOTT HT (High Transmission) glass prisms paired with fluoride-containing objective lenses, a combination that maximizes light throughput and delivers images with outstanding sharpness, contrast, and color accuracy from edge to edge. A sophisticated internal baffle system minimizes stray light, ensuring that high-contrast scenes—bright skies against dark tree lines, for example—are rendered without flare or washout. The result is an instrument that performs exceptionally well not only in bright daylight but also during dawn, dusk, and overcast conditions where lesser optics begin to struggle.

Build quality matches the optical standard. Every exterior lens surface is treated with Leica's HDC (High Durable Coating) for scratch and abrasion resistance, topped with AquaDura coating that causes water and grime to bead off rather than cling. The magnesium housing is rubber-armored for impact protection and sealed with nitrogen fill to a waterproof depth of 16.5 feet (5 meters), making these binoculars ready for sustained use in rain, snow, or humid tropical environments. Twist-up click-stop eyecups accommodate both eyeglass wearers and bare-eye users with multiple detent positions, while the center focusing wheel completes its full near-to-infinity range in just 1.25 turns—fast enough for tracking moving subjects without overshooting. At 12x magnification with 50mm objectives, the Ultravid HD-Plus delivers the resolving power needed for long-distance observation while maintaining a field of view of 5.7 degrees.
