Product Description
Product Description
Pentax Jupiter III
Manufacturers Description
There is no excuse not to have binoculars with the 160 grams and particularly small Jupiter III Universal binoculars, suitable in different situations. BaK4 prisms and multi coating on the built-in lenses, give this optical mini an exceptionally high contrast-rich, bright view. Jupiter III is the perfect partner for sporting events, concerts, as well as for hiking and travelling.
Inner Focusing
The Inner Focus function is critical to low-maintenance and long life guarantee. Exposure to airborne particles and moisture is avoided, thereby ensuring that no outside influences can penetrate the binocular housing and disrupt functionality.
High Quality BaK4 prism to enhance transmission and resolution
A prism is a complex optical element necessary to correct the image the right way up and reduce overall length of the binocular. In a prism, light travels through complicated angles and so the quality of the prism glass used is of significant importance. PENTAX uses exclusively high-index BaK4 prisms, made of very pure Barium glass.
