Generally, the smaller the binocs, the worse the optics. Not so the Legend Ultra-HD’s, which are impressively bright and sharp—especially in low light—for such a compact set (8.1 ounces). The center focus ring is smooth, and the twist-up eyecups are simple to remove for on-the-fly viewing. They’re a bit finicky to master, but at four inches long the Ultras stash perfectly in a jacket pocket—a great trade-off.
Binoculars with quality, fully multicoated lenses, which assist light transmission and help reduce glare, are finally becoming more affordable—and common. All four models here, including the compact Bushnell, have them.
