New Fully-multi-coated optics
Fully multi-coated lenses serve the essential purpose of maximising
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.
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 airbourne particles and moisture is avoided, thereby ensuring that no outside influences can penetrate the housing and disrupt functionality.
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.
