New edition of this product, expected to be available in fall 2026!
The new SPECTRA™ 8x 2.5-20x50i G4i Fiber further expands GPO's successful 8x zoom line at the premium end, offering a unique selling proposition in the market with its 2.5x to 20x magnification range. It is perfectly suited for both short distances and extreme long-range shooting. Thanks to its 50 mm objective lens diameter, it remains highly compact and easy to handle, making it an ideal choice for combination with clip-on night vision or thermal devices. The optical architecture is based on our highly successful 1.6-13x44i and delivers outstanding optical performance in terms of image quality (color rendition, light transmission, resolution, and edge-to-edge sharpness) as well as field of view. This is complemented by exceptional mechanical stability and maximum precision. Our optionally available GBT ballistic turret can be retrofitted to this model at any time, turning it into a true long-range specialist that—thanks to its high magnification and optical quality—is also perfect for observation and game identification."

From night hunting to driven hunts: GPO SPECTRA™ 8x 1.6–13x44i
The GPO SPECTRA™ is a joy to use. The build quality and features are impressive. In particular, the optional ballistic turret and the throw lever for the zoom ring are practical features. In combination with front-mounted attachments, the slim optic really shows its strengths.
For me, GPO is part of the perfect nature experience
As a birdwatcher, I pay attention to every detail – and this is precisely where the binoculars from GPO – German Precision Optics play to their strengths: brilliant optics, reliable robustness.
High quality for a great price!
The GPO SPECTRA™ 8x 1.6–13x44i is a riflescope that leaves nothing to be desired and meets all the requirements of modern hunting. You don't really expect this level of performance and high-quality workmanship in this price category. It was always a pleasure to hunt with this scope and have the confidence that I could rely on the optics. The scope always brought a happy grin to my face when I could use the full magnification range – for example, on driven hunts or during the roe buck rut, when it's never clear beforehand whether the game will appear at 10 m or 100 m.
GPO SPECTRA™ Pistol DOT - a new Red Dot Sight for sport shooters and hunters
In designing the new SPECTRA™ Pistol DOT, GPO paid particular attention to the requirements of ambitious and professional pistol shooters. [...] All this makes the new SPECTRA™ Pistol DOT an excellent optical sight for anyone who depends on rapid target acquisition in sports, hunting, or on duty. [...] Given the features and especially the included Picatinny mount, we also believe this is a very affordable and more than fair offer that you should definitely take a closer look at.
All-Around Scope at a Bargain Price
The SPECTRA™ 8x 1.6-13x44i is almost the legendary jack-of-all-trades and the ideal riflescope for the modern hunter who pursues wild boar at night with a front-mounted attachment and during the day on driven hunts. It is also perfectly equipped for the occasional mountain hunt or for hunting roe buck during the rut. For a front-mounted attachment, its compact design and reinforced housing are ideal. The illuminated reticle is top-class, and the optional ballistic turret also makes the optic ready for long-range shots. Conclusion: GPO is known for optics with a good price-performance ratio, and this is also true for the SPECTRA™ 8x 1.6-13x44i.
A lightweight pair of binoculars that makes no compromises on image performance
I first started using my GPO PASSION™ ED 8x32 over a year ago. […] After it has accompanied me halfway around the world – from the Arctic to the Middle East – and has been in use almost daily, I can assure you: the image performance is still as excellent today as it was on the first day. The mechanics of the focus wheel, diopter adjustment, and twist-up eyecups still run as smoothly and flawlessly as when they were new. The binoculars have withstood drops, been knocked against gates and fences, been frozen solid and completely soaked – and yet they still deliver a bright, razor-sharp image. The focus wheel requires only a minimal turn to jump from infinity to a close focus of just a few meters. This makes scanning the surroundings extremely fast and straightforward, regardless of the habitat. And I'll say it again: the binoculars are super lightweight. As a wildlife filmmaker, I usually carry over 40 kilos of camera equipment, so every gram counts. Knowing I have a lightweight pair of binoculars in my arsenal that makes no compromises on optical precision is a fantastic upgrade from all the binoculars I have used before.
Outstanding optics that are significantly more affordable compared to other brands
Recently, I have also been using my GPO PASSION™ 20-60x85 APO spotting scope. Another optically outstanding piece of equipment that is significantly more affordable than the models from many other brands. The focusing is smooth and precise, the construction is robust yet easy to transport, and the image remains crisp, sharp, and bright throughout the entire zoom range. Just like my GPO binoculars, it has now taken its place as my standard spotting scope whenever I need that extra magnification in the field. My camera work demands the world's best optics to deliver video footage that meets the demands of 8K resolution and projection in movie theaters. My eyes demand nothing less – and GPO delivers just that!
