Their traditional Porro prisms present you with a rich depth of field that allow you to more easily discern the distances between objects in your view for a real "3D" experience. Anti-reflection coated optics maximize the light entering the objectives to produce bright and clear images with accurate colors and crisp resolution. A knurled center focus wheel and an elastic polymer armored grip assist handling and give you precise control of the optic, while fold-down eyecups provide comfortable use with or without eyewear. Optical Performance - Powerful 10x magnification draws distant subjects in close for detailed observation and identification- Large 50mm objective lenses boost low-light capability for use in challenging conditions such as in the pre-dawn hours and late dusk- Traditional Porro prism optical path produces a rich depth of field with true stereoscopic vision for a more "3D" viewing experience- 5-element/3-group lens design helps to reduce fringing and distortion, making views appear sharp and flat with little edge curvature- Anti-reflection coated optics improve light transmission, contrast, and color rendition- Apparent angle of view approaches wide angle to reduce the appearance of distracting hand shake and the need to move your head side-to-side, so you see more of the scene in front of you
