These compact, inverted porro-prism models feature a durable dual-axis, single body design with synchronized IPD adjustment and full multi-coating for better light transmission. Aspherical lens elements give you edge-to-edge sharpness. They are a perfect “utility” companion for a multitude of applications.
Easily recognised by the dual-axis and classic inverted porro prism design, even our entry model has all the features of a starperformer: aspherical lens elements for edge-to-edge sharpness, multicoated lenses for great light transmission. 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 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.
