GPO Passion HD 8.5x50

This model is certainly the low light performer within the Passion HD series and makes an ideal choice for those who either often find themselves operating before dawn, just after sunset or in thick forests where the lack of quality light can be a limiting factor.
Not only are the larger 50mm objective lenses able to capture more light than the more commonly used 42mm ones, but when combined with a moderate 8.5x magnification they produce an exit pupil that is almost 6mm in diameter. This in combination with the very high-quality optics and coatings ensures that your eyes are supplied with more than enough light for you to perceive a bright image even in very low light conditions.
This GPO binocular also has a wide field of view making them great for scanning an area in search of an item of interest and it also helps to make it easier to quickly locate and then follow fast moving objects.
The 9.5mm of eye relief is excellent and used with the twist-up eyecups is more than enough for you to be able to view the full view without dark rings on the edges of the image, even whilst wearing eyeglasses.
At 3 meters, the minimum close focus on this model is good, but not excellent. Should you often like studying birds, butterflies, flowers or other objects from very close range, the 8x42 Passion HD may be a better option for your requirements.

About GPO Passion HD Binoculars

The Passion HD is the flagship series from German Precision Optics and as you would imagine, they truly boast an impressive array of world-class components and features that really do set them apart from the ordinary binocular. 
Incorporating some of the finest components, optical glass and coatings available, GPO’s flagship series is the Passion HD, which is are squarely aimed at the serious sports optics user.
Standout highlights on the body include a sealed magnesium chassis, aluminum eyecups and a central focus wheel with an integrated locking diopter correction mechanism. Whilst optically, the Passion HD series includes double fluorite containing ED lens elements, a Schmidt Pechan roof prism system that is both phase corrected and dielectrically mirror coated.
Available in a selection of magnifications and with either 42mm or 50mm lenses, there is a Passion HD binocular to perfectly suit most outdoor enthusiasts needs.

Important Features

These GPO binoculars sport a modern top-hinge body design and are built around a tough, yet relatively lightweight magnesium chassis. The polished microbridge is also made from magnesium and the multi-texture body armor provides both protection and a good level of grip.
Fully O-ring sealed, the Passion HD series is watertight to a pressure of 500 Mbars and with the interior filled with dry nitrogen gas, the internal glass surfaces are fog resistant. 
The eyepiece housings and twist-up eyecups are made from aluminum and feature multiple intermediate click stops to ensure you get the full view for use with or without glasses. These binoculars all have a centrally located focus wheel that also incorporates the lockable diopter adjuster within the mechanism.

Optical Properties

As well as their excellent chassis and exterior, the GPO Passion HD binoculars also feature a collection of premium level optical components and coatings:
Both models feature Schmidt Pechan roof prism system. The phase correction coatings prevent phase shift and thus help deliver a higher resolution image, whilst the dielectric mirror coatings are able to reflect more than 99% of the light across the full spectrum and thus boost both the image brightness and overall quality. 
The whole optical pathway is fully multi-coated with anti-reflection coatings and the objective lenses feature double HD lens elements (two fluorite containing lenses which are “cemented” together) that drastically reduces the distortions that cause color fringing. 
Exterior lens surfaces also have GPO’s proprietary "PASSIONdrop” hydrophobic coatings added to them that help keep the lenses free of water, oil, and dirt for easier cleaning and better views in all weather conditions.

Accessories

Whilst these binoculars come with the usual arrangement of accessories, their quality is anything but ordinary. A semi-rigid carry case provides an excellent level of protection, whilst the neoprene backed neck strap looks great and is very comfortable. Also included is a rain-guard, objective lens covers, cleaning cloth and instruction booklet.
