And definitely some people are more sensitive then others. Although I dislike 10x bins, the Noctivid 10x42 is truly phenomenal. Just started to test one. Optically and mechanically superb. Quite a l lot of CA though. Focuser oh so smooth just like EDG. Ergonomy is very ok, although the double bridge design feels a bit forced and improves nothing on the single hinge of the Ultravid. Of course they needed it for psychological reasons, to really attack the Swarovision.I now have high hopes for the Noctivid 8x32 because ease of view in the Noctivid is superb with 4mm EP. Hopefully the 8x32 will not be a double bridge design.</blockquote>
