Explore Scientific G600 ED Series 8x56 Binoculars

A premium 8x56 binocular with ED glass and dielectric phase-corrected BaK-4 prisms — the largest objectives in the G600 ED lineup, purpose-built for low-light performance at dawn, dusk, and under heavy cloud cover.

The 56mm aperture gathers 78% more light than a 42mm binocular and produces a generous 7mm exit pupil — matching the maximum pupil dilation of a fully dark-adapted eye. That means brighter images in the last minutes of usable twilight, when birds are still active and mammals are emerging. ED glass keeps colors accurate and eliminates the chromatic fringing that becomes especially distracting in low-contrast, low-light scenes.

The 19.3mm eye relief is the most generous in the G600 ED series, making these the most comfortable option for eyeglass wearers. Nitrogen-purged and rated IPX7 waterproof. The tripod socket is recommended for extended sessions — the larger objectives add some weight compared to the 42mm models.
