Enjoy a sharp, clear view while birding or traveling with the 8x40 Jupiter Binoculars from Pentax. Rubber armored for durability and a comfortable grip, these binoculars offer a sense of depth and a wide field of view, along with a close-focus distance of under 20'. The 40mm objective lenses admit lots of light for a bright view in even low-light conditions. The center focus adjustment knob is easy to reach so you can effortlessly dial in a tack-sharp image. For fully shake-free viewing, mount the binoculars on a tripod using a TP-3 adapter, available separately.
