Vortex Kaibab HD 15x56
The Kaibab HD series of Vortex binoculars consists of only one pair of binoculars with the parameters of 15x56. It features low-dispersion glass objectives and BaK-4 glass roof prisms, set in the Schmidt-Pechan system and phase-correction coated. The producer claims all air-to-glass surfaces are coated by multilayer antireflection XR coatings which are supposed to ensure a high transmission level and good colour rendition.
The buyer gets caps, a strap, a case with its own strap and an original tripod adapter included in the product bundle. The set of binoculars comes with a lifetime guarantee.

There are not many sets of binoculars with 15-15x magnification and 50-60 mm objective diameter on the market. We managed to find some, though, in order to compare the tested device to them.. As you can notice when it comes to basic parameters the group is quite homogeneous. Only the Docter sticks out a bit with its objective diameter and weight and the Leica differs in price – mainly because of the rangefinder used. Fields of view are quite decent in this group (eyepieces on the level of 60 degrees or more) and range from 4.0 to 4.4 degrees.
The Vortex Kaibab HD 15x56 is not a cheap device, quite the opposite in fact – the price of over 1000 Euro is impressive even in the case of such an objective as big as 56 mm. It is a segment for the most serious market players. Can you justify such a steep price? It seems that yes, you can. An average chromatic aberration correction level is the only slip-up of the tested Kaibab HD, being low despite using low-dispersion elements in objective lenses.
In the case of other categories, we don’t see any weak results, only average, good or very good ones. Overall the device got 137 points in our test. It is a score only a tad over 1 point worse than that of the Docter Nobilem 15x60 BGA, so praised by us - a set of binoculars with a similar price tag, a significantly greater weight, being much less handy. If you are interested in such parameters, you can’t afford the Swarovski SLC New 15x56 and you are terrified seeing the dimensions and the weight of the Docter, the Vortex Kaibab HD 15x56 will be a good choice for sure.
