Pentax AD 9x28 Waterproof binoculars

Ricoh/Pentax AD 9x28 Waterproof

Pentax AD 9x28 WP binoculars with 9x magnification and a 28mm front lens. In contrast to the traditional 8x and 10x magnifications, this Pentax A-series binocular has a slightly less common 9x magnification.

Like most compact binoculars, these are ideal for hiking and nature walks.

The Pentax AD 9x28 WP is compact in physical size, making it easy to pack and take with you almost anywhere. Like almost all binoculars on the market, the Pentax's robust binocular body is covered with a rubber coating. In addition to protecting the body from bumps, the coating also helps to get a grip on the binoculars, even when the binocular body is wet. Not everyone will think about it, but the dark coating also prevents reflections and dampens the impact of the binoculars, which is important when observing shy birds and animals without being noticed.

The soft rubber-lined and knurled focus ring is comfortable under the index finger. The focus mechanism is designed so that when focusing from the closest focusing distance of 3 meters to infinity, approximately 480 degrees of movement are required, which is a little more than one rotation of the focus ring. This means that focusing from close to far and from far to close is fast.

The binoculars do not have a tripod thread, but with the help of a separately purchased universal binocular adapter, you can attach the binoculars to a tripod, for example.
