GPO Passion HD 10x50

The 10x50 configuration on these GPO binoculars generates a 5mm exit pupil, which is almost as large as that which you get with the 8x42 Passion HD. Thus if adding a little more weight and size is not an issue for you and you need an instrument that can provide you with both a reasonably good low light performance and a little more reach than what an 8x power can give you, then this binocular makes an excellent choice.
At 103 meters wide at a distance of 1000 meters, the field of view on this model is excellent for an instrument with a 10x magnification, which makes finding and then following anything in your view that much quicker and easier to do.
Whilst these binoculars will really excel out on the open fields, in the hills or along the coast in good light and at slightly longer ranges, all the aspects above combined contribute to making an excellent choice of binocular for the wildlife observer, hunter or even bird watcher who operates in a variety of different locations and in a variety of light conditions.
The eye relief on these binoculars is very long and when combined with their high-quality twist-up eyecups it makes certain that you will be able to get your eyes the correct distance behind the ocular lenses to achieve the full image, with or without wearing glasses.

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.
