These are chinese, made by Sicong and sold by various oems, Opticron, Viking, Williams, etc. For build quality they are not upto the Japanese, but they are light, optically I found they more than adequate. No gross disrortions, like the really low end market. The eye relief is good 20mm, close focus 1.5m, CA quite low. A capable binocular, in my opinion. I am, despite the name, not a perfectionist and prepared to balance cost v performance. Buy at a reasonable price and enjoy.
