I am happy to test it for you Andrew, just send it on down to Canberra
I haven't tried the Swarovski zoom but if it is as good as the Zeiss zoom then you have a good one.
The Zeiss showed a little FC in my F5.6 scope but it was very very sharp, on axis it was as good as anything I have used.
I think a lot of people would be swayed away by the short zoom ratio of the Swarovski and the Leica zooms of 2x.
