Hi Ilkka
I too think that all top end roof prism bins available today have more CA than is really acceptable. (Maybe this is the curse of having a Nordic name?)
I tried the Leica Ultravid 8x42 yesterday (looking at scopes at an RSPB reserve, and couldn't resist spending 10 minutes outside with a pair) and was struck by the small size and the rather large amount of CA even in dull conditions. It was so obvious but is never mentioned in reviews.
Regarding the Zeiss, I reckon we should wait and see. Minox produce some bins with ED elements, including a 10x58, and they are said to have excellent contrast. Incidentally the Zeiss 8x30 BGAT, an old design, have almost no CA. Not being an optical designer, it's hard to comment further.
