With dimensions of 1.6 x 4.1 x 4.3 inches and weight of only 10.6 ounces, the PENTAX DCF SW 10×25 binocular is indeed ultra compact and a true pocket binocular. It also has a distinctive advantage with the dual hinge design, making it exceptionally portable (can fold up closer than any roof prism pocket with only one hinge).
