Pentax UP 8-16×21 Binoculars

The Pentax UP 8-16×21 Binoculars deliver exceptional versatility and optical performance in a compact, portable package. With a Uni-body Porro prism system, these binoculars incorporate a dual-axis, synchronised eyepiece adjustment that ensures stable, and clear viewing. Fully multicoated optics combined with aspherical lens elements provide excellent edge-to-edge sharpness, vivid colours, and high contrast in all lighting conditions.

With a zoom range of 8–16× magnification, these binoculars allow users to easily adjust between wide-angle views and detailed, long-distance observation. At 8× magnification, the real field of view is 5° (86.65 m at 1,000 m), while at 16× magnification, it narrows to 3° (51.79 m at 1,000 m), giving flexibility for different scenarios. The 21 mm objective lenses efficiently gather light, making them suitable for outdoor use, sports events, and nature observation even in low-light conditions. The binoculars provide a minimum focusing distance of just 3.02 m, perfect for close-up observation, while the eye relief of 14 mm at 8× and 11 mm at 16× ensures comfortable viewing, including for eyeglass wearers.

These centre-focusing binoculars also include a tripod socket for stable observation, making them ideal for extended outdoor sessions. Measuring 111 × 111 × 53 mm and weighing approximately 309 g, they combine portability with high functionality.
