Ricoh announces Pentax Jupiter series of binoculars

Ricoh Imaging Americas Corp. announced the PENTAX JUPITER series of porro-prism binoculars. The four models in the new series feature large-aperture objective lenses, with a choice of magnifications ranging from 8x to 16x.

Jupiter 12×50

The PENTAX JUPITER series binoculars are designed for comfortable viewing, even for first-time binocular users. The series includes models with magnifications of 8×40, 10×50, 12×50 and 16×50. Each incorporates a large objective lens with an aperture of more than 40 millimeters. The optical element has been treated with a multi-coating process to minimize unwanted reflection of light, delivering a well-defined subject image, free of flare and ghost images.

The binoculars have also been designed to be simple to use and comfortable to hold, with an easy-to-access focus ring and an exterior rubber coating that helps to ensure a secure grip on the body and minimize the possibility of slippage.

The PENTAX JUPITER series is compatible with the optional and currently available TP-3 tripod adapter for use with a tripod.

The PENTAX JUPITER series binoculars will be available in April 2022, with the following manufacturer’s suggested retail pricing: JUPITER 8×40 – $89.00, JUPITER 10×50 – $99.00, JUPITER 12×50 – $109.00; JUPITER 16×50 – $119.00.
