"So, here we have yet another GPO binocular offering exceptional ergonomics and really good optics for a very decent price. I say this in light of a cursory examination of other 8x or 10 x 56 models, built around Abbe-Koenig prisms. The Zeiss Conquest HD 8 x 56, for example, has a build quality quite comparable to the GPO Passion, but its field of view is slightly smaller(125m@1000m), its weight slightly heavier(1265g), its eye relief lower(18mm), its close focus distance much longer(3.5m), and possesses a light transmission of 90 per cent, lower than that of the GPO Passion, even with ED glass. But that instrument retails for more than twice the price of the big GPO light bucket! Or consider the fluorite containing Maven B5 10 x 56 costing a few hundred pounds more than even the Zeiss Conquest HD but with the same light transmission as the GPO Passion(92 per cent or so). Seen in this light, the GPO Passion 8 x 56 offers tremendous bang for buck and absolutely deserves great success in the burgeoning sports optics market."

About this product
Model: gpo_passion_ed_56_8x56_blk
Part Number: B400
GPO Passion 56mm binoculars designed in Germany and manufactured to a very high standard.
Large 56mm objectives make this an excellent binocular for astronomy and other low light observing.
Premium glass with custom multi-layer optical coatings and Abbe-Koenig рrіѕms deliver very high optical performance.
Sharpness extends across almost the entire field of view.
Contrast and colour accuracy is excellent and light transmission is 90%+.
The body is built around a durable and lightweight magnesium chassis. Fit and finish is very impressive and tactile surfaces provide good grip.
They are also water-proof, fog-proof and have a water repellent coating on the objective lenses (rain drops roll off) so can be used with confidence in all weather.
NOTE: These are large binoculars. They can be handheld but for longer observations they are best used mounted on a tripod.
