A few months back in a discussion with Mr. Stephen Albercht (Leica Business Development Manager for Sports Optics) he mentioned to me that the less-than-perfect optical quality of an stabilized binocular is a concern for Leica. I am guessing the feedback control systems and the electronic actuator mechanisms are too complex for an optics-only company to make. There could also be issues with patent protection by the Japanese companies. The Zeiss 20X60 is an entirely different mechanism. It doesn't use electronic feedback control but rather a mechanical suspension trick. I have read its patents but I admit that I didn't quite figure out its mechanism.</blockquote>
