Vortex Diamondback HD 10x50 binoculars

This is my first pair of binoculars (not counting the ones from Biedronka for 60 zloty), so it's difficult for me to compare it to others. The build quality is solid, it's heavy (apparently that's a feature of a good pair of binoculars), and the adjustment knob works smoothly. The dioptre adjustment on the right eyepiece moves with resistance, so it's hard to move it by accident. The eyepiece cover allows for two different distances from the lens and works flawlessly. The case could be a bit bigger – in my opinion, it's a little too tight. When I pull the binoculars out, the objective covers automatically come off. How you carry it with the straps is a matter of taste; I can't imagine walking through the forest with them on my chest, although for hunters or in tactical situations it might make sense. That's why I modified it to be worn on the thigh. Most importantly – the image is sharp, and the colours are natural, but only in the centre. At the edges, the image becomes blurry. There's some chromatic aberration, though I've heard even roof binoculars costing several thousand have it. At night, when looking at streetlights, there’s no star effect or any interference. Overall, I'm satisfied, but I was expecting more. I hoped for a better effect. I'd like to compare the image with another pair of binoculars costing half as much, to have a point of reference. And finally – it bothers me that Vortex USA is a product made in China.

Everything as expected. The binoculars provide a clear image even after dark. They are lightweight and easy to carry in the included case. During winter weather outside they did not fog up during use, but upon entering a warm interior it seemed to me that one of the eyepieces fogged up from the inside. Their lightness is matched by solid workmanship. I am convinced they will serve for a long time.

The image is clear and bright even in low evening light. I am not familiar with the technical details so I will not judge them, but if you are not expecting professional-quality image, this is perfectly sufficient – there’s no need to spend several thousand zlotys. Focusing is easy to adjust. The device is light and not too big – it might not fit in a small pocket, but it takes up little space in a backpack. The case does its job. The binoculars seem sturdy, although I haven’t tested their durability. In case of damage, there’s a lifetime Vortex warranty, which sets it apart from other brands. After a few weeks of use, I am satisfied.
