Hi! Just got the Kowa BDII 10x42 from Amazon, and can underline Henrys infos. In the center I really like the image, but as soon as you are leaving the center, very soon, you get massive CAs, and blurry image. Too much CAs in that price range for me, so gets returned. I liked the Maven C1 10x42 I had for a day, but that model was a lemon, I had to return. Maven did not reply to my mail about that, so no chance to get a good working C1 for me here at the moment.
