The Pentax 8x21 UCF R is a popular small binocular and an excellent value. Weighs only 7.1 ounces! Push-down eyecups are comfortable with eyeglasses on. Multicoated optics and aspheric lenses provide sharp optics. Two hinges are geared together so you don't experience the hinge "flop" found on other relatively inexpensive binoculars. Includes simple vinyl case, lens caps and strap.
