A: Roof Prism Binoculars requires precise manufacturing of finely aligned prisms and lenses to deliver sharp views in a rugged, internally focused system. The streamline design lets you position your wrists and arms in a natural way for more relaxed viewing. Porro Prism Binoculars use a simpler system that cost less to manufacture and provides a very pleasing 3-dimensional view, great depth of field, and a wide field of view because of the well-spaced barrels.
