With the Swarovski they have the only one thing in common-green color, so I do not understand why this two products shoud be compared. 10x40 Saidwinders retailed for about $190.00. They cannot be competing with the big three (Leica, Swarovski and Zeiss). Docter (former Zeiss Jena) and high end Nikons might be getting closer to the Swarovski , but not quite yet
