About GP Optics
A new player in the high end optics market is German Precision Optics, who rather like Best Binocular Reviews (BBR), shorten their name to GPO!

Germany & GPO USA
As their name suggests, GPO has its roots in Germany, where all of the designing and engineering takes place, but they also have a North American division based in Midlothian, Virginia.

From what I can gather (and please feel free to correct me if I am wrong), the company was created by two guys, both of whom held top positions at Carl Zeiss Sports Optics:

Firstly there is Richard Schmidt, who was the CEO at Zeiss GmbH and who now owns and runs the German division of GPO GmbH which owns the GPO brand.

Then there is Michael Jensen, who had held the post of president at Zeiss Sports Optics, LLC and who now heads up GPO USA.

USP & Ethos:
GPO have what they describe as a "unique corporate structure" that they say enables German Precision Optics to produce superior quality instruments with even better features, but at the same sort of prices that you would expect from the other top tier brands from Germany and Europe (I assume they mean companies like Zeiss, Swarovski and Leica, etc.).

Or the other way of looking at it, they can deliver instruments of a similar level to the other top end brands, but at a lower price.

GPO Range
Currently German Precision Optics have a couple of riflescope options (the GPOTAC series and the PASSION series) and two ranges of binoculars:

GPO Binoculars

Being new to the arena and I guess because their main focus is on the very high end, premium instruments niche, their range is quite small at the moment, but I expect this will grow over time. Even so, what they do have looks very interesting with some unique features that are well worth highlighting:

GPO Passion HD Binoculars

GPO Passion 10x42 HD BinocularsThe flagship series from German Precision Optics, the Passion HD series consists of five roof prism models, which as you would expect boasts a whole flotilla of premium features and stats, but which also have a couple of very interesting aspects and innovations:

The interesting one for me is that they highlight the use of more than one extra-low dispersion element within the lenses.

GPO call this their "Double HD glass technology" and they say it further reduces chromatic aberrations and that whist this is a feature commonly used within high end photography lenses, it has now been brought to the field of sport optics.

I am not actually sure if or how many other brands do this with their ED lenses as almost none go into details, but whatever the case it seems that it must be an improvement on their standard ED lenses used on their cheaper Passion ED models (see below).

  • GPO Passion 8x42 HD BinocularsFully Multi-Coated Optical system
  • GPObright™ lens coatings - that they say has a transmittance of 99.7%
  • Double HD Lenses
  • Hydrophobic Coatings on exterior lens surfaces
  • Locking diopter located on the central focus wheel
  • Aluminum eyecup housing
  • Magnesium Chassis and Bridge
  • Fog & Waterproof

GP Optics Passion HD Binoculars come in five different configurations:

Depending on the model (with the larger higher powered ones being more expensive) the RRP ranges from $1299.99 to $979.99 in the US or in Europe: €1299.99 to €979.99. As for current price levels, this has already dropped and so it is well worth checking and comparing current retail prices:

GPO Passion ED Binoculars

GPO Passion 10x42 ED BinocularsWhilst still very high quality, the Passion ED series sits just below that of the HD series.

Apart from design differences to exterior and a range of available colors, the main differences (besides the cost) is the use of "normal" ED glass lenses rather than the Double HD lenses that I discussed above.

As far as I can see, GPO Passion ED binoculars also lack the hydrophobic exterior lens coatings used on the HD's:

Main Features


GPO Passion 8x32 ED Binoculars in Desert Sand Color32mm Passion ED's come in four different color options which include "desert sand", "charcoal black", "deep green" and "dark brown earth".

Another difference between these cheaper ED models and that of the HD's is that I think these have the diopter adjuster located on right eyepiece in the usual position as there is no mention of it being lockable and on the focus wheel in the description.

Models & Specifications

The GPO ED series binoculars come in mid-sized 32mm configurations as well as 42mm options. There are currently no 50mm Passion ED models:

Model FOV Eye Relief Min Focus Weight Dim
8x42 341ft 19.5mm 8.2ft 23.2oz 5.7x5.1"
10x42 314ft 16mm 8.2ft 24oz 5.7x5.1"

Recommended retail prices for the German Precis si on Optics Passion ED binoculars goes from $399.99 for the 10x42 model, to $359.99 for the 8x32 making these look like really great value for money ED binoculars, for current prices in your country, check out the link below:

GPO Passion Binoculars

GPO Passion 10x56 BinocularsThe latest addition to the GPO brand is their couple of offerings in the standard Passion series.

Currently, there are just two large 56mm models available. Apart from the larger lens size, the main difference between these and that two higher specification Passion HD and Passion ED ranges is that instead of using Extra-low dispersion glass elements within the lenses, this series goes back to using standard low dispersion glass.

Whilst this makes them cheaper to manufacture, the difference in terms of the aberrations that are reduced is not always clear as I have often come across well made non-ED glass binoculars that perform as well and even sometimes outperform binoculars using ED glass when it comes to the amount of color fringing that is displayed in the image. For more on this you can check out the following articles:

So apart from this and the larger lens size, the GPO Passion 8x56 and 10x56 binoculars look to have just about all the other main features incorporated into them as the higher value ED Passion models:

GPO Proprietary Technologies

GPObright™ is a German Precision Optics lens coating process that they say increases level of light transmission through each surface of an optical element:

Normal uncoated high-performance glass can reflect up to 5% of light that arrives at an optical surface and so does not continue throughout the optical system.

With GPObright™, the lenses are vacuum-coated with these coatings, which they say will transmit up to 99.7% of the light through each surface.

Thus if you take into consideration the entire optical system the total level of transmittance is about 92% which offers an excellent low light performance.
