The Sun Optics' 7x50 Porro Prism Binoculars utilizes a traditional Porro prism optical path with fully multi-coated optics to provide users with bright and clear high-contrast views with accurate color rendition and a rich depth of field, for a truly immersive experience. Its exceptionally long eye relief and wide exit pupil make for comfortable use during long observations, and ensures that the light exiting the oculars completely cover dilated pupils in low-light conditions so users can enjoy full views without vignetting

Complementing the optical performance is a lightweight and durable aluminum alloy chassis that is wrapped in a protective slip-resistant armor. Raised palm-pads improve grip comfort and grip security. Each optical tube is nitrogen-filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperatures and environmental conditions.
