Compact binoculars with 8x magnification. Inside the body, which has an original shape, hides an optical system based on a prismatic block of the Porro type. The lenses of the Pentax 8x21 UP binoculars have a diameter of 21 mm and an aspherical shape (it almost completely eliminates distortion at the edges of the field of view). The lenses and elements of the prismatic system are coated with a full multi-layer anti-reflective coating, which provides a clear and contrasting picture with natural color rendition. The device is available in several color options (the body can be black, blue or pink).
