 Minox HG Aspheric BinocularsAspheric optics give better image quality than standard spherical surfaces but are harder to produce. Minox has incorporated them into these models, along with many other high-performance techniques, to produce one of the finest binocular ranges available today. High-quality Schott glass, magnesium bodies for light weight and strength, waterproof finish and argon gas filling combine with precise engineering to ensure you get the ultimate experience from your binoculars. This quote from Bird Watcher's Digest sums up some of their qualities: " In our optical quality tests, the Minox HGs were excellent. They also have some of the nicest-feeling engineering and smoothest-turning focus knobs we've found in any binocular. The addition of a distance scale on the focus knob (made possible because the wheel turns less than one full rotation in going from closest to most distant) gives the HG binocular the unique function of acting as a range meter. The central focus wheel also serves as the easy-to-turn, locking diopter adjustment wheel. The eyecups, with gentle detents, twist out with unusual smoothness and precision. Eye relief for glasses wearers is excellent, as is the optical quality. Several of our testers remarked that the HG gave a nice feeling in the hand. We judged it to be a great buy for someone looking at the upper end of the mid-priced field, for quality comparable to the high-end binoculars " |
