Hi Chuck--
So yes, the Leica UVHDs arrived, and my overall reaction is "wow." I intend to make a comparison with the Endeavors (and to a lesser extent, the Conquests) at some point down the road. But for right now, if I had to characterize the view, I would say "quiet, refined, beautiful." No they're not sharp to the edge. No, they don't have perfect CA control. But they're just so beautiful to look through. The image is bright but calm, highly detailed, beautifully colored, and almost totally free of any scattered light artifacts (crescents, veiling glare, etc.). The aesthetic quality of the image is something that doesn't make it into, say, an Allbinos review (they've got this bin rated below the Vanguard, for example). It's like tasting a fine wine, or hearing a familiar piece of music given a fresh and beautiful interpretation. It makes you want to pick up the binocular, rather than leave it on the shelf.
The focuser is smooth with no slop, a bit slower than the Conquest, and while stiffer (the Conquest has the lightest focuser touch I've encountered), it is easy to use and gives a feeling of precision. The binocular balances very nicely in my hands. And most importantly perhaps, it is easy to look through. No fussing with blackouts or proper eye placement.
I'm very happy with them in this initial period. After I've had some time with them, perhaps I'll have nitpicks--we'll see. But they're certainly a cut above anything else I've looked through, save perhaps the Zeiss HT with which I had a few moments in a camera store.
