Steiner enters the big glass market with its 15x56mm Big Horn porro-prism binocular that comes ready to mount to a tripod. The 44.4-ounce binocular features BAK 4 prisms and optics that are fully multi-coated. The binocular also has Steiner's Sports Auto-focus system that keeps all subjects in focus from 50 yards to infinity. The system requires no further focusing once adjusted to the user's eye. Profiled wrap around eyecups keep out sidelight and the glasses have just less than 4/5-inch of eye relief. The eyecups can be pushed back for use by those who wear eyeglasses. The glasses offer a field of view of 210 feet at 1,000 yards. Contact Steiner, Dept RS, 97 Foster Road, Suite 5, Moorestown, NJ 08057; (800) 257-7742; www.steiner-binoculars.com.
