As my old Leica Trinovid 8x42 were getting a bit old, I decided to buy the Kowa 8.5x44 Genesis for my birdwatching trip to Cape May, New Jersey. Compared to my old binoculars I found these provided superior image quality and stability, but were a bit heavier, which I don't mind. These are great birdwatching binoculars and I wish I got them earlier.
