The Specifications of Nikon Lookout II Action Binoculars

Nikon makes binoculars as well as cameras. Its Lookout II line was designed for viewing birds and other wildlife. The company retired the line in the mid-1990s and replaced it with Action 10x50 binoculars. Lookout II binoculars, which cost about $200 when new, are available in resale shops and through private sales. The Lookout II was marketed to what Nikon refers to a "prosumers," a level of customers that falls between professional ornithologists and amateurs with intermediate skills.

  1. Range

    • The Lookout II has a field range of 10x50. The magnification is 10x, with the objective diameter at 50x. Objective diameter refers to the amount of light let in by the two large lenses of the binoculars. The larger the objective diameter, the more light that passes through the optics.

    Focus and Eyepieces

    • The Lookout II has focus screws on each eyepiece to adjust the stereo configuration. After bringing what you want to look at into view, you turn the adjustment dial between the optics barrels to bring the object in focus. The eyepieces have rubber rims that roll back to help people who wear glasses see through the binoculars.

    Exterior Materials and Fog-Free Coatings

    • To keep the lenses from fogging, Nikon injects nitrogen into the barrels. The barrels are coated with hard rubber to improve your grip when using the binoculars outdoors. The Lookout II also came with a chest and shoulder strap to secure the binoculars to your body.

    Weight and Size

    • Lookout II binoculars weigh approximately 27.9 ounces. The binoculars measure 8.5 inches long and 5.5 inches wide when folded.
