About this product

The Pentax 8x25 U Series UP Binoculars are extremely portable, lightweight and compact, and feature an easy to carry and stow, fibreglass reinforced polycarbonate housing that is corrosion and impact resistant. The housing material is also temperature-resistant allowing for its 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.

The 25mm objective lenses are fully multicoated to reduce reflection and maximise light transmission to produce the brightest images possible. Aspherical lens elements virtually eliminate distortion, especially around the edges, and correct for lens astigmatism which can prevent sharp focusing. The BAK4 Porro prisms also incorporated in these compact Pentax binoculars deliver edge-to-edge image clarity and sharpness with a 5ø angle of view. Ideal for use in all environments, these binoculars will be your ideal companion out in the bush or in the theatre, thanks to their durable design.

In addition to observing distant scenes, birds and game, the minimum focus of 1.92m allows you to study close objects like animal footprints, marks or landscape features in close detail. The binocular also features a 2.1mm exit pupil, a 15mm eye relief and sliding rubber eyecups which are ideal for spectacle wearers.

Featuring an ergonomically designed countered single piece frame for easy and comfortable grip, these compact binoculars offer a synchronised interpupillary adjustment and diopter adjustments. This unique Uni-body design enhances durability by locking objective lenses in a single housing and synchronising the eyepiece movement. This minimises moving parts and assures these binoculars will function properly and clearly for years to come.

Also included with your Pentax binoculars are a carrying case, a neck strap, and eyepiece covers.
