Steve,
Thanks for your comments.
A couple of quick questions, but perhaps, if you can be bothered, you could post your answer on the Canon 10x42 thread so this branch of the discussion could continue there.
First, what is the price in Germany?
Secondly, when you say that the Canon was much sharper than the Leica, do you mean centerfield sharpness also, or only edge sharpness. Off-center sharpness in the 10x42 Ultravid is not spectacular, and Canon's field flatteners should easily provide much better off-axis performance. Dead center there could be a noticeable difference also, but if the difference is dramatic, then the Leica must indeed have been a lemon. Leica is very rugged, though, so simply being a demo should not compromise its performance. Any binocular which stands up well to the Ultravid in sharpness, brightness and contrast is definitely top-class.
