RICOH/PENTAX PENTAX SP WATERPROOF 8X40 Binoculars

Optical Features

• New fully multi-coated optics maximize light transmission, reducing flare and ghosting for a clear, crisp view.
• Phase correction coating enhances image quality in roof prism binoculars.
• Protective nano-technology lens coating repels water, oil, dust, and dirt, increasing durability.
• BaK4 prisms provide a perfectly round exit pupil and clear, unvignetted images.
• Aspherical lens elements in eyepieces reduce aberrations for edge-to-edge sharpness.

Construction and Durability

• Waterproof design with JIS Class 6 rating, allowing submersion up to 1 meter (3 feet).
• Nitrogen purged to prevent internal fogging and protect against dust ingress.
• Unique hydrophobic coating on outer lenses causes water droplets to bead and slide off, maintaining visibility in rain, snow, fog, or condensation.
• Magnesium alloy body provides toughness and lightweight handling.
• Rubber armoring offers superb shock and impact resistance.

Design and Usability

• Long eye relief design enables comfortable viewing, especially for eyeglass wearers.
• Helicoid three-stop eyepiece rings allow fine focus adjustment for maximum comfort.
