These compact, inverted porro-prism models feature a durable dual-axis, single body design with synchronised inter-pupillary distance adjustment. They are a perfect "utility" companion for a multitude of applications. In one compact and lightweight binocular you have the power to observe with 8 to 16x magnification by simply turning the central wheel. What's more, the aspherical lens elements ensure edge-to-edge sharpness, while BaK4 prisms and multi-coated lenses enhance brightness and contrast.

New Fully-multi-coated optics Fully multi-coated lenses serve the essential purpose of maximizing the amount of light passing through a lens, thereby prevent flare and ghosting from interfering with your view. Pentax applies multiple layers of coatings to every surface of every element and prism in the full Sport Optics line-up. These fully-multi-coated optics assure the maximum light transmission resulting in a clear, crisp view of the world.

BaK4 prisms Due to its outstanding refractive index, the BaK4 glass prism found in all Pentax Sport Optics is highly acclaimed for its perfectly round exit pupil and clear, unvignetted image.

Aspherical lens elements Edge-to-edge sharpness is a vital element to comfortable viewing. To achieve this, we utilise aspherical lens elements in our eyepieces. This is a specially shaped lens design that reduces aberration to a minimum.

Inner Focus Optics Design This sophisticated optical design is critical to low-maintenance and long life guarantee. Exposure to airborne particles and moisture is avoided, thereby ensuring that no outside influences can penetrate the housing and disrupt functionality.

Long eye relief design Design The long eye relief offered in all Pentax Sport Optics allows the viewer to see the entire field of view clearly and effortlessly. This is especially beneficial to eyeglass wearers, and allows viewing for extended periods of time without added eye strain.

Helicoid four-stop eyepiece rings: Permits fine adjustment for maximum viewing comfort. Exterior rubber coating: Provides the binoculars with superb resistance to shocks and impacts.   Back to top
