On the other hand I owned an early pair of 8x42 Trinovids BA's that showed no CA under any viewing conditions,only wish I had not sold them. Also the Nikon LXl's show more CA than the original LX due to the fact that the latter had lead and arsenic in the glass. One of the reasons for the use of ED,fl glass etc in binoculars today is to compensate for the lack of heavy metals in optical glass.As always thanks for an interesting review.                                                  fiddler.</blockquote>
