Not only do the Phenom ED binoculars showcase superb image quality, they are ergonomically designed to be compact and comfortable to use. With RubberGuard armoring encasing the magnesium-aluminum alloy chassis, the Phenom ED offers outstanding durability at a fraction of the weight. The two thumb indents in the RubberGuard armor on the bottom of each barrel improve grip and user accessibility.
In most standard binoculars, one of the problems is that the objects in the center appear to be in sharper focus than those around the edges.
Conversely, if you adjust the center focus wheel until the objects on the periphery are perfectly focused, the image in the center may be slightly unfocused.
By utilizing a field flattener doublet lens in the optical system, the Phenom ED binoculars produce clear and true color images from edge to edge.
