The Pentax UP 8X25 Binocular is Pentax's UP line of Porro Prism models available in four power strengths to suit your needs.
Features
Pentax's highly portable and functional 8x25 U-Series UP Binocular employ an innovative unibody design that locks the objective lenses into the body with the eyepieces set on a synchronized dual-axis mechanism that ensures they stay symmetrical in relation to the centre axis of the optic when adjusting the interpupillary distance.
The Pentax UP 8X25 Binocular features niceties such as short minimum focusing distances, comfortable rubberized shells and dioptric corrections that will not be changed accidentally.
The 25mm objective lenses are fully Multi-coated to reduce reflection and maximize light transmission to produce the brightest images possible. Aspherical lens elements virtually eliminate distortion, especially around the edges, and corrects for lens astigmatism which can prevent sharp focusing.
Designed for easy carrying and stowing, the Binocular features a lightweight fiberglass reinforced polycarbonate housing that is corrosion and impact-resistant.
The housing material is also temperature-resistant allowing for their use in extreme climates while reducing expansion and contraction-wide temperature variations can cause, which can make the optical components move out of collimation over time.
