Two eyes, a wide field, and no setup at all · review
A 10x50 with BaK-4 prisms carrying an additional silver mirror coating, published with its field of view, weight, dimensions and close focus.
The bottom line The one binocular here that can be compared on numbers rather than words — and it is heavy, which the numbers also tell you.
Ninety-four metres of field at a thousand. Seven hundred and forty grams without the case. A hundred and seventy-two by a hundred and forty-six by sixty millimetres. Three metres of close focus. Fully multi-coated lenses, BaK-4 prisms with an added silver mirror coating. That is a complete description, and it is rare enough on this shelf to be the main reason to take this pair seriously.
Just over five degrees. Sweeping along the Milky Way at that width is genuinely comfortable, and finding a comet from a chart is much easier than it is through a narrow field.
Seven hundred and forty grams is at the heavier end. Held to the eyes, that becomes noticeable within a few minutes — which is an argument for a chair, a monopod or a tripod adapter rather than against the binocular.
Dust caps, a comfort strap, a case, a cleaning cloth and a manual, each listed separately. A strap described as comfort-oriented is worth something on a 740 g pair.

American and British Amazon stores list it in local currency, which the euro range above sets aside.

It is the width of the view at a distance of 1000 m — the usual European way of publishing field of view. It converts to a little over five degrees of sky, which is a generous sweeping field for 10x.
A prism working below the critical angle needs a reflective surface, and silver is a good one. The maker also credits it with reducing ultraviolet, which is stated without a figure and cannot be compared.
