Opticron Oregon 4 PC Oasis 10x50 Binoculars

The Opticron Oregon 4 PC Oasis 10x50 Binoculars are designed to provide first-time and occasional users with outstanding optical performance, making them an excellent choice for wildlife observation, birdwatching, countryside walks and general outdoor exploration. Combining powerful 10x magnification with large 50mm objective lenses, they gather plenty of light to produce bright, detailed images, particularly during dawn, dusk and other low-light conditions.

Built around a high-quality BAK4 roof prism optical system, the Oregon 4 features fully multi-coated lenses, phase-corrected prisms and Opticron's Oasis-C+ high light transmission prism coating to maximise brightness, contrast and colour fidelity. The result is a sharp, natural viewing experience across a wide range of outdoor environments.

The lightweight yet durable aluminium alloy and polycarbonate body is fully waterproof and nitrogen filled to prevent internal fogging, ensuring dependable performance whatever the weather. A sophisticated twin-relief rubber armour provides a comfortable, secure grip, while the wide focus wheel allows smooth and precise focusing. Long 22mm eye relief and twist-up eyecups offer comfortable viewing for both spectacle and non-spectacle wearers.

With a close focus distance of just 2.5 metres and an integrated tripod adapter socket for extended viewing sessions, the Opticron Oregon 4 PC Oasis 10x50 is a versatile binocular that's equally at home observing wildlife, enjoying scenic landscapes or exploring the night sky.
