Brock,
I suppose this thread is wandering pretty far from new Swarovski binoculars, but I'll add a little to Ronald's experience with Optolyth.
The Alpins use a very similar optical design to the Swarovski Habichts, conventional cemented objectives and simple 3 element Kellners in the narrow field models and 6 element Erfles in the wide field models, but there the similarities end. I bought a 10x50 Alpin long ago. I found it to be flimsily constructed with seriously undersized prisms which reduced the true aperture to about 45mm. The Ceralin multi-coating was probably the best thing about the binocular, very high transmission with neutral colors, combined with the simple design made for a very bright contrasty image, but I wouldn't be at all interested in these at Deutsche Optik's price. The Nikon 8x30/10x35 EIIs are superior in every way. I suspect you can find performance equivalent to the Optolyths in $100 Chinese binoculars.
