I bought the 15-45x65 Diascope just before Christmas. I have the Cabelas Big Sky 20-80x80 and while its ok, it does ont have the resolution of the Zeiss. I have been playing a little with my digital camera and the Diascope. Pretty cool. I like this spotter a lot. I chose it over the Swarovski because if its length and weight. I got a free neoprene cover for it also. No complaints so far.
