Kahles don't even come in at a close 2nd
Swarovski polishes there glass to a much better standard
and they also have there swaro bright lens coating
I have used Kahles before and believe me there not even a close 4 th
And just incase you didn't know swarovski owns Kahles
I have the Kahles and Swarovskis in 10x42's. I have the Swarovskis and my son has the Kahles. The Kahles are very clear but a bit less bright. They are much better than a lot of binos but they are not the same as the Swarovskis. You get what you pay for!! They are a bit lighter though.
