Kowa 8×33 Genesis 33 PROMINAR XD Binoculars

Description

Featuring dual XD objective lenses, the Kowa 8×33 Genesis 33 PROMINAR XD Binoculars spreads an expansive 420-foot field of view at 1000 yards (8.0-degree actual). The 4.1mm exit pupil and 15mm eye relief provide fast sight picture acquisition. At 20.8 ounces, its thick magnesium body feels denser in hand than typical 32mm travel glass.

Two pairs of Prominar XD extra-low dispersion elements feed phase-corrected Schmidt-Pechan BaK-4 roof prisms coated in C3 dielectric mirror layers and KR dirt-resistant coatings. The magnesium alloy chassis is sheathed in dark green rubber armor, measuring 5.2 by 4.8 by 2 inches and weighing 20.8 oz (590 g). Nitrogen filled and water-resistant, it features an internal center focus wheel tracking down to 4.9 feet (1.5 m), a locking diopter, and twist-up eyecups.

Key Features of Kowa 8×33 Genesis 33 PROMINAR XD Binoculars

A reference mid-sized optic designed for discerning field ornithologists who require chromatic correction without packing a heavy 42mm binocular. The wide 8.0-degree angle provides sweeping situational awareness, while the Prominar XD glass renders plumage patterns with authentic fidelity.

• 8x magnification through 33mm objective lenses with a 4.1mm exit pupil
• Four Prominar XD optical elements eliminating chromatic fringing
• Schmidt-Pechan roof prisms treated with C3 dielectric mirror coatings
• Expansive 420 ft field of view at 1000 yd (8.0-degree actual angle)
• 15mm eye relief with multi-stop twist-up rubber eyecups
• Short 4.9-foot close focus distance suited for macro insect inspection
• Nitrogen gas purged magnesium alloy chassis with dark green rubber armor
• Integrated locking diopter adjustment ring and front tripod adapter socket

Prominar XD Optics & C3 Prism Transmission

Kowa fits four XD lens elements containing fluorite crystal characteristics, completely suppressing secondary spectrum fringing along backlit branches. C3 dielectric prism coatings reflect over 99 percent of light across the visible spectrum, yielding true color neutrality and high edge-to-edge sharpness across 88 percent of the frame.

Magnesium Chassis & Macro-Focus Mechanics

The thick magnesium alloy body protects internal prism collimation from heavy mechanical shocks, maintaining factory alignment over years of trail use. The internal center focus wheel turns with smooth, grease-damped drag, and the central diopter dial locks firmly to prevent setting drift.

• Internal center focus wheel sweeps from macro distance to infinity with fluid resistance
• Locking diopter ring preserves custom focal calibration against pack friction
• O-ring sealed nitrogen chambers eliminate internal lens fogging during freezing rain
