I just compared the Zeiss 10x42 FL to the Swarovision 10x50 at Cabella's in Grand Junction Colorado and I couldn't believe how much better tha big Swarovision was. It made the Zeiss look poor and the Zeiss is a good binocular! I still prefer the Swarovision 8.5x42 for it's bigger fov though but for more magnification the Swarovski is the way to go. There was NO question it was much better.
Careful Dennis, don't be tempted - remember you didn't like the weight of the Canons or the 56m Zeiss! (And I'm betting that you'll keep the SV 8.5x42)
