Attaching the strap to the binoculars is achieved in the usual way using a slider and threading it through the eyelets on the instrument. This tried and tested method works well enough and means you can easily adjust the strap for length. For a more complete picture, below are the measurements that I took of them in a range of different states: The level of fuzziness right at the edges of the view is very minimal (almost non existent) and once again, in my experience is about as good as you could ever hope for.

Unfortunately the chromatic aberration correction is a serious flaw of the GPO. The Swarovski Swarovision EL 8.5x42 and the 10x42, both being among my favourite pairs of binoculars, are as close to perfection as it is only possible and yet noticeable chromatic aberration on the edge of the field remains their only slip-up. The GPO Passion HD 10x42 fares even a tad worse than these two. While playing with the GPO I also had the Swarovision 8.5x42, the Zeiss Conquest HD 10x32, the Leica Ultravid BL 10x42 and the Trinovid BN 8x42 at my disposal. In the aberration category the GPO fared the worst of all of them. It reflects badly on the tested model. I would be more understanding if the Passion HD offered the widest field of view available on the market at the same time but, unfortunately, the tested binoculars are nowhere close to the Nikon Monarch HG or the Zeiss Conquest HD in that aspect. The diopter adjustment mechanism is concealed beneath the focus knob: you pull it out to reveal the mechanism, which is then twisted in either direction toUchôa Passos, T., et al. (2015).

extra bit of comfort. The eyecups extend with a helical twist mechanism, and there is one position between fully in or out. Each position is marked with a very new optic isn’t particularly exciting. So what makes this at all different? Well, for starters, this optic is coming out in a higher quality set it at the center point. But if you have unequal eyes, make the adjustment and note what that setting is, so that if you lose it somehow, you don’t have to gothe field; this is good performance for this trait. The focus knob is large with raised ridges on the rubber coating to improve the grip. We were Thus in terms of image brightness, this leads me to rate these GPO's right at the top of what you can expect to get from a 10x42 binocular. Comparing them once again in a wide range of scenarios and light conditions, once again the colors and level of contrast in the image looked to me to be pretty much identical to my alpha benchmark 10x42.

During last 2-3 years we’ve seen many new companies which offer top-of-the-range binoculars and spotting scopes making their debut on the market. Not so long ago we informed about a launch of Blaser binoculars, produced by German Sport Optics. Their prices are comparable to those of the most expensive Leica, Swarovski or Zeiss models. Binoculars priced at 1000 Euro level are also being offered by such companies as Maven Optics or Tract Optics (so far they have been available mainly on the American market); what’s interesting they have managed to earn very positive opinions. German Precision Optics is the next player which joined that club. It has been set up by former employees of German optics industry and, at the beginning of the second quarter of 2017, they managed to launch two series of binoculars. impressed by how smoothly and easily this knob turned, even brand new out of the box. This was well done! Getting from close focus to infinity

The eye-cup housing on these GPO Passion binoculars is made aluminum and not plastic as which is often the case on cheaper instruments. The padded section is attached very firmly and even though it is made from a thin rubber, is no less comfortable than what I would consider to be normal. the visual field when you are sharp in the middle. Again, this isn’t a drastic issue - people naturally tend to look through the center of an optic and Their official outer dimensions are fairly typical for a 42mm binocular and so not too much to report here. At the other end of the instruments I noticed that the objective lenses are inset by 9mm/0.35in and may benefit from a ‘lens-hood’ effect, reducing any glare. The rain-guard is pretty standard. It fits over the eye-cups perfectly making it easy to replace, but at the same time is tight enough so that it does not fall away by accident. I also like the design in that it has a flexible bridge meaning that you can fix it to the binocular no matter your IPD
