Whether you use it for indoor or outdoor events, you will be pleasantly surprised by the clarity and sharpness of the image… and surprisingly affordable too.

New Fully-multi-coated Optics

Fully multi-coated lenses serve the essential purpose of maximizing the amount of light passing through a lens, thereby preventing 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.

Aspherical Lens Elements

Edge-to-edge sharpness is a vital element to comfortable viewing. To achieve this, we utilize 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.

Other Features

Helicoid four-stop eyepiece rings that permit fine adjustment for maximum viewing comfort.

Exterior rubber coating that provides the binoculars with superb resistance to shocks and impacts.
