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.<br><br><b>Aspherical lens elements</b><br>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.<br><br><b>Inner Focus Optics Design</b><br>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.Pentax UP 8x21.
