Last summer I bought a pair of Kahles 8x42's. They are a very good binocular for the price. A week later I was loaned pair of Leica's to try. I went out at late afternoon till dusk to compare the two pair. As good as the Kahles were, they were noticeably inferior to the Leica's.
I returned the Kahles for a pair of Leica 8x42's
